Top Five DIY Annoyances When Working on Your Vehicle

hood up fixing carMany DIYers relish the opportunity to work on their vehicle, whether it’s performing routine maintenance or installing the latest performance upgrade. Sometimes, however, what should be a relaxing and satisfying few hours spent under the hood on a weekend afternoon with the game on in the background turns instead into a knuckle-busting, tool-throwing lesson in DIY frustration.

We’ve all been there – victims of Murphy’s Law. Whatever can go wrong, will, and the chances of it happening rise in tandem with the degree to which you’re feeling rushed or under pressure to get the job done.

Here’s my Top Five List of DIY Annoyances. This isn’t an all-inclusive list, so let’s hear what your biggest frustrations are under the hood.

Plastic engine and under-car covers. Lift the hood or crawl underneath most modern vehicles and you’ll see plastic – a lot of it. Plastic shrouds cover the engine, the battery, and pretty much everything else you might have a need to access under the hood. It’s no better down on the ground with plastic blocking precisely the spot you need to place a wrench. Depending on whom you believe, all that plastic serves a purpose – according to vehicle manufacturers – or it’s been placed there to thwart DIYers. Regardless, its presence makes your job that much more difficult and time-consuming. And, more often than not, the plastic screws or clips holding the shrouds in place break when they’re removed. I prefer a plastic-cover free, roomy engine compartment, circa 1973, in which to perform my best work.

Lost – or as I tell my wife – “temporarily misplaced” tools. It’s a simple job – one that shouldn’t take more than 45 minutes and one for which you have all the necessary tools close at hand. Or so you think. The one tool that you must have for the job, and that you know you do have, isn’t where it should be. In fact, it isn’t anywhere. Did you loan it to someone? Leave it in the shed? Mistakenly throw it away? You now wind up spending more time searching for that tool than it would have taken you to complete the job. Put the tools away where they belong every time.

Fixing that which is not broken, or, “If it ain’t broke, don’t fix it.” Sometimes you’re unsure exactly what the problem is so you start fixing things that you think may be the culprit, only to find out they’re not. On the other hand, you might be overconfident that you know exactly what the vehicle maintenance problem is so you fix it, and quickly learn it wasn’t the problem. Case in point – the Honda engine on my wood splitter suffered from an intermittent failure to start. I was sure it was the rust build up on the flywheel magnet. It wasn’t. Then it had to be the spark plug. Nope. Followed by the low-oil switch. Wrong again. Finally, I struck gold by cleaning some water and junk out of the carb bowl. Finding the right fix can be time-consuming, costly, and frustrating, but it’s important.

Doing more harm than good. When does a routine carb adjustment turn into a head removal? After you drop something down the intake. In the blink of an eye, what should have been an easy, inexpensive task just turned into an expensive vehicle maintenance nightmare because you deposited a screw, nut, washer or some loose change down there. Sure, you can tell yourself that it fell in the gravel driveway and that’s why you can’t find it. You’ll soon learn the truth when you start the engine. It’s happened to the best of us – good intentions of fixing one part are punished with the realization that you just broke something else, and it’s going to be a lot more difficult and time-consuming to repair.

Other people. Even if you’re living by yourself in a cabin in the woods you still have to deal with other people, and their mistakes, when it comes to servicing your vehicle. Don’t think so? Have you ever been under the hood of a vehicle someone owned before you and found yourself shaking your head in amazement, wondering how and why the previous owner made a repair the way they did? Ever pull up to a self-service car wash or air pump, deposit some coins and only then find out that someone before you broke the equipment? Ever get some bad advice from a well-meaning friend or brother-in-law who “had that exact same model and knows exactly what the problem is.” We’re all human and we all make mistakes. Be ready for it.

Working on vehicles can be a tricky business or hobby and one that’s full of surprises. Expect the annoyances, learn to roll with them, appreciate the time you get to spend under the hood, and share your pet peeves with us. You’ll feel better after you do.

Crucial Cars: AMC Javelin AMX

1974 AMC Javelin AMX

From timeless icons to everyday essentials, Crucial Cars examines the vehicles we can’t live without.

For this installment, Gearhead’s Garage puts the spotlight on AMC’s entry in the Pony Car wars, the Javelin AMX

Largely overshadowed by the Chevrolet Camaro, Pontiac Firebird and Ford Mustang, (and to a lesser degree the Dodge Challenger and Plymouth Barracuda), the AMC Javelin AMX was akin to RC cola battling Coke and Pepsi. That doesn’t mean it was a bad choice in the Pony car segment (so-called because the Mustang is credited with starting this sporty segment back in 1964). Far from it, the Javelin AMX was just a different flavor. And plenty of performance enthusiasts found it downright sweet.

Note that we are talking about the four-passenger Javelin AMX here that was produced from 1971-1974, not the two-passenger version that was based on a shortened Javelin body/platform, just called the AMC AMX and produced from 1968-1970. Certainly the earlier version was cool in its own right, being the only American car of that time other than the Corvette to seat just two, but its appeal was limited and AMC made the decision to continue it after 1970 with the Javelin body and its backseat fully intact.

1971 AMC Javelin AMX

1971 AMC Javelin AMX

Cue it up
As it was now the top performance version of AMC’s Javelin, the 1971 AMX shared its styling. This meant the Javelin’s Corvette-like front fender curves, long hood and semi-fastback roofline were key styling cues, as was the full-width taillight panel. Marking it as the top dog in the AMC kennel were a mesh grille, a rear spoiler and a few options, such as a cowl induction hood and a big “T” stripe for the hood, that were not available on the standard Javelin. Inside the AMX, bucket seats and a console were standard and the dash curved around the driver. Along with that cockpit feel, the dash and door panels featured a metallic “engine turned” appliqué which further enhanced the AMX’s decidedly sporty vibe.

Extra performance for the AMX
With an overall length of 191.8 inches, the Javelin was about two inches longer than a ’71 Mustang and about four inches longer than a ’71 Camaro. Under the hood, a 360 cubic-inch, two-barrel V8 with 245 horsepower was standard, and could be hooked up to either a three-speed automatic or three-speed manual gearbox. Most buyers stepped up to either the 360 4-barrel (285 hp) or 401 4-barrel (330 hp) V8, either of which could have the automatic or a four-speed manual. Any guesses as to which powertrain we’d go with? The optional “Go” package included either the 360-4 barrel or 401-4 barrel V8 along with dual exhausts, the “twin grip” rear differential, the cowl induction hood with the T stripe, 15-inch (rather than 14-inch) wheels, a firmer suspension and a Rally gauge package.

As you were
For 1972, there were just a few changes to note for AMC’s sporty coupe. A smaller, 304 cubic-inch V8 was the standard engine, with both 360s and the 401 optional. As with other American cars, engine output ratings changed from “Gross” to “Net”. The previous Gross ratings were measured with the engine itself running on a stand, as opposed to the more realistic Net ratings which measured its output with accessory pulleys, exhaust and transmission all installed.

Yes, the ’72 engines lost a little power due to drops in compression that allowed them to meet tougher emissions standards and run on lower octane gas, but they didn’t lose nearly as much as simply comparing gross to net numbers might falsely indicate. That said, the 304 made 150 hp, the 360 2 barrel V8 was now rated at 175 hp, the 360 4 barrel with dual exhaust made 220 hp, and the big dog 401 was rated at 255 hp.

1973 AMC Javelin AMX with Cardin option

1973 AMC Javelin AMX with Cardin option

As the mid-’70s approached, luxury started to replace performance as a big selling point. For 1973, AMC offered an optional Cardin (yes, Pierre Cardin, the clothes designer) interior package for the Javelin and it could even be had on the AMX. Fully embracing the outlandish ’70s, the Cardin package featured black upholstery sporting wide stripes of white, orange and fuchsia running rampant over the seats, door panels and even the headliner. Visually, the only notable external change was the taillights going from the previous full width strip design to four semi-squared off units. Fortunately, for those who actually wanted performance more than plush trimmings, you could still specify an AMX with the 360 or 401 Go package and a Hurst-shifted four-speed.

The following year, 1974, would be the Javelin’s — and hence the Javelin AMX’s – last. Other than the Cardin package disappearing from the options roster, nothing changed for ’74.

Top Tuners for American Muscle

2015 Yenko Camaro

2015 Yenko Camaro

Today’s war among American performance cars easily rivals the one waged so fiercely during the 1960s and early ’70s. In addition to the factory muscle car offerings, you had upgraded versions offered by certain dealerships. Owned by rapid enthusiasts, these dealerships were hell bent on giving their customers (and themselves) a reputation for street battle supremacy.

These dealers — such as Yenko Chevrolet, Mr. Norm’s Grand Spaulding Dodge and Tasca Ford — would gladly build up your Camaro, Challenger or Mustang to a performance level seemingly limited only by your nerve and financial status. Pavement burners such as a Yenko Camaro sporting a 427-cubic inch big block gave acceleration junkies serious one-upmanship on their buddies who had “settled” for a stock SS396 Camaro. Likewise for Dodge fans who wanted a hopped up Dart and Ford fans who, before the factory made it available, wanted nothing less than a 428 Cobra Jet V8 in their Mustangs.

Nowadays, modern factory performance cars leave little argument for such improvements. Does anyone really need more than what we’ve seen show up in Chevy, Ford and Dodge showrooms the last couple of years? Specifically, how could you possibly want more than a 580-horsepower Camaro ZL1, a 662-hp Mustang Shelby GT500 or a 707-hp Challenger Hellcat? For those performance buffs who live by the “too much is not enough” credo, there are a number of companies around who are more than willing to boost these beasts beyond their already crazy capabilities.

2012 Ford Mustang Shelby GT500 Super Snake

2012 Ford Mustang Shelby GT500 Super Snake

Mustang fans who were disappointed to see the Shelby GT500 absent from the all-new 2015 Mustang family need only contact Shelby American. Click away and you’ll see they offer the newest ‘stang in the 750-horse “Super Snake” version that along with all that go-power sports upgraded brakes and suspension as well as various carbon-fiber body components. If you do own a 2011-2014 GT500 and you’ve deep enough pockets, you can have them turn your car into a 1,200-hp track day monster.

1969 Yenko Camaro

1969 Yenko Camaro

On the other side of the battlefield, Chevy Camaro enthusiasts can once again hit the streets with a Yenko Camaro, thanks to Special Vehicle Engineering who acquired the rights to use the hallowed dealership’s name. Just like the good old days, a 427 cubic-inch V8 is stuffed under the hood, only this time it’s the modern small-block “LS7″version. Formerly used in the Corvette Z06 and currently seen in the new Camaro Z/28, the LS7 normally makes 505 horsepower. For the Yenko, it is supercharged and further tweaked to make a thumping 700 horsepower. Proper homage is paid to the original Yenko Camaros via a scooped hood and 1969-style “YSC” (Yenko Super Car) body graphics.

2015 Challenger Hellcat

2015 Challenger Hellcat

As it did in the early ’70s, the Dodge Challenger faces off against those rivals from Ford and Chevrolet. Right off the showroom floor, you can get over 700 horsepower in a new Challenger, provided you spring for the Hellcat version. That’s enough thrust to sling you down the quarter mile in just under 12 seconds. Should you find that somewhat lacking, you can have the good folks at Hennessey Performance beef up your Hellcat to the tune of 852 horsepower. Short of strapping a Space Shuttle’s Booster rocket to the trunk lid, there’s not much else that you could do to turn your Hellcat into one of hardest accelerating vehicles wearing four tires and a license plate.

Whether you keep your modern performance car bone stock or choose to have it modified by an aftermarket tuning firm, there’s no denying that today’s car wars make this a great time to have a license for us with 93 octane flowing freely through our veins.

Crucial Cars: GMC Sierra

2016 GMC Sierra

From timeless icons to everyday essentials, Crucial Cars examines the vehicles we can’t live without.

For this installment, the Mechanic Next Door does some heavy lifting, delving into the GMC Sierra pickup’s history and looking at the newest model.

Max and Morris Grabowsky may not be household names, but they cemented their place in automotive history nonetheless. In 1901 the Grabowsky duo built a truck prototype in Pontiac, Michigan, and went on to form their company – the Rapid Motor Vehicle Company – a year later. It didn’t take long for the brothers’ truck-building efforts and success to attract competitors’ attention, with General Motors buying them in 1909. Just three years later at the New York Auto Show, the name GMC Trucks would make its debut.

And so begins the story of GMC’s Sierra – a leader in the category of full-size pickups and a nearly identical twin to Chevy’s Silverado truck lineup. It wasn’t until the 1970s, however, that GMC would debut the name Sierra, using it to designate their trucks’ trim level, until 1987 when Sierra began serving as the permanent name for GMC’s full-size pickups.

GMC’s early, 1960’s-era pickups – before the Sierra name change – were designated as either “wideside” or “fenderside” – the latter corresponding to what many drivers today refer to as “stepside” pickups with fenders that flare out over the rear wheels. GMC also was one of the first to use numbers to indicate its trucks’ hauling capacities using the “1000”, “1500”, and “2000” designations that are common today in one form or another among all the major truck manufacturers. A “K” attached to those numbers indicated a GMC truck with four-wheel drive, and there were just two trim levels available – base or Custom. The standard engine was a 236-cubic-inch inline six delivering 135 horsepower.

Through the mid-1960’s, GMC trucks underwent a suspension change, additional engine options, and cosmetic changes to freshen the truck’s appearance. One of the most notable changes, and perhaps the start of pickups’ migration to becoming more than just work vehicles, was the debut of air conditioning in 1965.

1973 saw GM completely redesign its pickup truck line with longer wheelbases and the debut of a four-door crew cab. Engine choices ranged from a 100-horsepower, 250-cubic-inch inline six on the low end to a 240-horse 454 V8. GM’s next complete overhaul of its Sierra truck line wouldn’t occur until 1988 with trucks sporting a third more glass for improved visibility and a marked focus on more luxury items, such as upholstery and instrumentation.

That 80’s-era “luxury” pales in comparison to today’s model, considering that the 2016 GMC Sierra sports such innovations as advanced safety features and a 4G Wi-Fi Hotspot. The pickup’s evolution from being strictly a work vehicle to becoming a multi-purpose vehicle today is clearly evident on GMC’s site for Sierra, where a review of the vehicle’s interior receives precedence over its capabilities – something that would have been unheard of when trucks were meant solely for hauling and pulling. This old school Sierra’s transition into a show vehicle shows that there’s clearly a lot of life left for these pickups even when their days of doing hard work are over.

That’s not to say that new Sierra’s lack anything in the performance department. Its 6.2L V8 cranks out 420 horsepower, which GMC says is more than any other light-duty pickup. And, according to GM, the available EcoTec3 5.3L V8 engine delivers the best V8 fuel economy available among any full-size pickup. Balancing that power with control is Hill Descent Control, allowing for less nerve-wracking downhill journeys in rough terrain, and the Eaton Locker which automatically locks the rear wheels when slippage is detected.

Other automatic technology features aimed at assisting drivers include the Lane Keep Assist which helps drivers avoid drifting out of their lane by automatically correcting steering, and IntelliBeam which activates or deactivates Sierra’s high beams based on traffic conditions. Forward Collision Alert provides audible and visual alerts to help prevent collisions while the Safety Alert Seat vibrates as a warning signal to drivers.

Technology inside Sierra’s cab that’s aimed at driver convenience rather than strictly safety includes IntellilLink for customizing and organizing a variety of media, Apple CarPlay for syncing phones to the IntelliLink system, the previously mentioned 4G WiFi hotspot, and OnStar’s RemoteLink app to remotely start the vehicle, pinpoint its location on a map, and monitor the vehicle’s mechanical functions.

Available in four trim levels – Sierra Base Trim, SLE, SLT, and Denali, Sierra’s base MSRP is $27,275, and heads higher from there. After decades of popularity among truck buyers and features that give drivers what they want, the Sierra’s popularity doesn’t show any signs of slowing down.

Ways to Boost Power without Breaking the Bank

Much like an elite athlete’s ability to rapidly breathe allows them to perform stronger, so it goes with your car’s engine. Whether you drive a ’69 Chevelle or an ’09 Civic, the same principle applies. Get more air in and out and your engine will make more power and run stronger. This is why forced induction (i.e. turbocharging and supercharging) is so popular as a means for, literally, pumping up an engine’s output. That’s great, but unless it came on your car it’s also easily a $5,000 and up modification.

If you want to improve your car’s performance without spending a lot, then you’ll want to focus on cost-effective ways to make that mill breathe like an Olympic decathlete without tearing into it. In other words, consider these following bolt-on mods that will give you the best bang, or should we say breathing, for your buck.

Edelbrock Pro-Flo 1000

Edelbrock Pro-Flo 1000

Golden Oldies Take a Breather
Going with a less-restrictive air filter setup than what the factory has supplied has long been a staple of performance enthusiasts. Those who own an old American car from the ’60s and ’70s typically favor a round, open-element air cleaner that sits over that carburetor. Although some old muscle cars actually came standard with these types of filters, or even trick hood scoops that funneled colder outside air to the intake, more often than not you’d see a closed housing that breathed through a snorkel-like fixture sticking out of its side. Other options for those golden oldies include Edelbrock’s iconic, triangular “Pro-Flo 1000” (formerly known as the “Lynx”) open-element filter.

 

K&N Cold Air Kit

K&N Cold Air Kit

Something for the Younger Ones
When fuel injection became more widespread in the ’80s, air filter assemblies took on more complex configurations that continue to this day. The latter is due chiefly to being equipped with various sensors that keep tabs on things like intake air temperature and velocity so the computers can adjust fuel metering accordingly. The air filters themselves are typically buried within black plastic boxes. The aftermarket quickly came to the rescue with low-restriction, cold-air kits that typically feature a semi-conical open-element filter. K&N, in particular, makes well-engineered kits that are known for their high quality and wide range of applications.

Ok, Now Exhale
So now that your engine can inhale more deeply; it’s time to turn your attention to the exhaling side of the equation – the exhaust. Before model year 1975, when catalytic converters (“cats”, for short) came on the scene to clean up exhaust emissions, the default performance-enhancing setup was pretty straightforward: exhaust headers running to true dual exhausts with a crossover. Nowadays, the ideal setup is pretty much the same, albeit with high-flow cats plumbed into the system. Of course you’ll want to check with your state’s emissions laws beforehand regarding replacing the cat(s), as some states may only allow factory replacements.

Still, going with a full engine-to-tailpipes system can be rather complicated (ask anybody who’s installed headers) and expensive, plus that labor is probably beyond what most shade-tree wrenches can do. The good news is you don’t have to go that far. Those looking for a cost-effective and minimal hassle upgrade should consider a “cat-back” exhaust system. It is just that, a system that bolts up after your car’s catalytic converter(s). With its freer-flowing pipes and lower-restriction muffler(s), a cat-back exhaust system lets your engine exhale easier and sounds pretty cool in the process.

Cat-back exhaust

Cat-back exhaust

Regardless of what you drive, there are plenty of great choices for a cat-back system. Popular brands include Borla, Dynomax and Magnaflow. Even within each manufacturer’s product line, there’s great variety, sonically speaking. You’ve got systems that are fairly quiet at idle and part throttle that then growl gratifyingly when you step into it. And then you’ve got the more aggressive setups that proudly make their presence known whether you’re burbling at a light on the boulevard or grabbing gears as you rocket up a freeway on-ramp.

 

For these power-boosting auto parts, along with all the tools you’ll need to complete the job, Advance Auto Parts will get back to the garage fast. 

Crucial Cars: Chevrolet Camaro

From timeless icons to everyday essentials, Crucial Cars examines the vehicles we can’t live without.

For this installment, Gearhead’s Garage puts the spotlight on Chevrolet’s iconic sport coupe, the Camaro.

1969 Camaro SS350 with RS package

1969 Camaro SS350 with RS package

Back when the Chevrolet Camaro debuted, the Beatles were making albums, color TV was a new novelty and the Vietnam war was escalating. Chevy’s sleek new number, an answer to Ford’s super successful Mustang launched a few years prior, came onto the groovy scene to get its slice of the “pony car” pie. In the nearly half century since, the Camaro has stayed true to its roots by providing enthusiasts with an abundance of styling and performance at an affordable price.

Right back at you Ford
Ford’s Mustang, launched in the spring of 1964, was an immediate smash success. It introduced a new automotive segment that became known as the pony car — an affordable, relatively compact sporty coupe with long hood and short rear deck proportions. Loosely based on Chevrolet’s compact Nova, the Camaro was introduced for 1967. And so began a rivalry that continues to this day, one as fierce as the Yankees versus the Red Sox, or Coke versus Pepsi.

Available in both coupe and convertible body styles, the Camaro could be had with a wide array of powertrains. One could have anything from a 230 cubic-inch, 140-horsepower straight six on up to a storming 396 cube V8 cranking out 375 hp. Transmissions consisted of two- and three-speed automatics as well as three- and four-speed manuals.

The trim levels similarly ran the gamut and included the base Camaro, the fancy RS (Rally Sport) with its hidden headlights and added interior/exterior garnishment, the muscular SS that could be had in either SS350 or SS396 guise, and then there was the Z/28. Getting its name from the actual option code, the Z/28 was a street-legal road race machine sporting a firmer suspension and a high-output 302 cube V8 matched exclusively to a four-speed stick. Seriously underrated at 290 hp, the high-revving 302 made more like 350-375 horses. The Z/28 was a rare sight for that first year, as only 602 were built.

The next year saw minimal changes. Visually, the easiest way to tell a ’68 from a ’67 is the lack of the triangular vent windows which gave a slightly sleeker look to the ’68. The 1969 Camaro is for many enthusiasts the one to have. Although essentially the same as its other first-generation brothers under the skin, the ’69’s more aggressive styling boasted flared character lines that came off the front and rear wheel wells, giving an impression of speed and power that the upper versions could easily back up.

Throughout this first generation there were also several rare, ultra high performance versions. Specially ordered through the COPO (Central Office Production Order) program via dealers such as Yenko and Berger, these Camaros had beefy 427 V8s rated at a conservative 425 horsepower. The top dog was the Camaro ZL1, of which just 69 were built for 1969. A ZL1 also featured a 427 V8, but in this case it was of exotic all-aluminum construction, yielding a big block brute that barely weighed any more than a 327 V8.

Following a tough act

The second-generation Camaro debuted as a 1970 ½ model. Taking the long hood/short deck aesthetic to a new level, Chevy definitely had the looks nailed. Initially available in base, RS, SS and Z/28 versions, this Camaro could be packed with power, as the Z/28 came with a high-output 350 rated at 360 hp, while the top SS 396 (actually now displacing 402 cubes) again made 375.

Sadly, as with all other car makers, Chevrolet’s engine output started to slide as the mid-’70s hit due to tightening emissions standards. Indeed, the SS was dropped from the lineup after ’72 while the Z/28 went on hiatus for ’75 and ’76 seemingly out of shame, to return in mid-’77 with just 170 hp from its 350 V8. Still, these cars provided some driving fun by way of their quick, relatively agile handling and rumbling exhausts. Thankfully, engine output started to creep up as the 1980s hit, with the ’80 Z28 making 190 hp. Styling got increasingly flashy, culminating in the ’80 (and ’81) Z28 which seemed inspired by its Pontiac Trans Am cousin, what with bigger graphics, an Air Induction hood scoop, functional fender vents and wheel flares.

Less weight, more power

1981 Camaro Z28

1981 Camaro Z28

The third generation of the Camaro spanned 1982 through 1992. Through these years, one could choose a base Camaro, a luxury-themed Berlinetta (later the LT) or the performance-oriented Z28 and later, IROC-Z. Downsized, this Camaro was also up to 500 pounds lighter than the one before, and also heralded the debut of fuel injection and a four-speed automatic transmission.

Now that technology and engineering savvy allowed engines to efficiently meet emissions standards, output climbed through the decade. The 1982 Camaro’s power lineup started with an anemic, 90-hp four-cylinder engine, moved up through a 2.8-liter, 112-hp V6 and topped out with a 5.0-liter (305 cubic-inch) V8, rated at 145 hp, or with available Cross-fire fuel injection, 165 hp. Midway through 1983, a 190 hp “High Output” 5.0 liter became available, while two years later a 5.0-liter with Tuned Port Injection debuted, making 215 hp. Named for the International Race of Champions (which used identically-prepped Camaros), the Camaro IROC-Z also debuted for 1985 sporting huge for the time 16-inch wheels, a track-tuned suspension and, unlike the Z28, a monotone paint scheme along with tasteful “IROC-Z” bodyside graphics.

1988 Camaro IROC-Z

1988 Camaro IROC-Z

Literally big news came around for 1987, when a 5.7-liter (350 for you old-schoolers) V8 once again became available in a Camaro, now with tuned port injection and 225 horses. Sadly, it could only be hooked up to the automatic gearbox, but by now the 5.0 TPI engine could be had with a five-speed manual, the latter being the enthusiasts’ choice. The next year, the Z28 was dropped, essentially being replaced by the IROC-Z due to the latter’s massive popularity.

Other than the V6 growing from 2.8- to 3.1 liters (now at a respectable 140 hp) and the debut of a driver side airbag, not much changed until 1991, when the IROC-Z was dropped due to Dodge getting the race contract. And so, the Z28 returned once again to the lineup, now with an IROC-Z-like monochrome body treatment, color-keyed alloy wheels and taller rear deck spoiler. The 5.7-liter TPI engine now thumped out a stout 245 horsepower. Although 1992 marked the 25th anniversary of the Camaro, celebration was limited to a badge on the dash and the availability of a commemorative package consisting chiefly of dual hood/deck stripes.

With Part Two of this installment, we’ll cover the fourth-, fifth- and upcoming sixth-generation Camaros.

A number of Camaro enthusiast sites provide advice as well as classifieds for cars and parts for sale. You may want to check out Camaro Forums and Camaro Source. Furthermore, acceleration times can be found on zeroto60times.com.

Talkin’ Carbs…As In Carburetors vs. Fuel Injection

1970 Camaro Z28 350

1970 Camaro Z28 350

Back in the day, “the day” being the thousands from the mid-1950s through the early 1970s, American performance cars’ fuel delivery system of choice was four-, six- or even eight-barrel carburetion. More often than not you saw a single four-barrel sitting atop the engine’s intake manifold. But a trio of two-barrel carburetors (called “Tri-power” and “Six pack” among other cool sounding names) could be had on some Detroit iron during the ’60s and ’70s, such as the Pontiac GTO, Chevy Corvette, Plymouth Road Runner and Dodge Challenger.

For monsters such as the early ’60s Impala SS409 and the ’67 Shelby GT500 Mustang, nothing less than two four barrel carbs (“dual quads”) would do. Carburetors were not without their pitfalls, however, as tasks like changing jets, synching those multi-carb setups and generally getting them perfectly dialed in were usually best left to a shop with all the necessary tools and expertise.

Fuel injection in those early years was very rare, but available on a handful of American cars during some of those years. For example, certain 1957 GM products from Chevrolet and Pontiac offered it just that one year.

As fuel injection was relatively new technology, the bugs weren’t fully worked out so it was dropped as an (admittedly expensive and not popular) option for the full size GM cars the very next year. It did, however, continue to be optional on the Corvette, right through 1965.

As performance-themed American cars passed through the 1980s, fuel-injection came online bigtime.

Thanks to their ability to monitor and make millisecond adjustments for various parameters such as intake air temperature and idle quality, these modern-era F.I. systems were instrumental in bringing back performance after the dark days of the mid-’70s to early ’80s. Being able to precisely control the air/fuel mixture, they allowed engineers to fine tune the engine to both meet tough emissions standards and offer increased power output. Other benefits are smoother operation all around, such as when driving in high elevations and in very cold or hot weather.

fast efiWhich all brings us to the question of: should you have an older performance car, should you keep the old carbs or make the switch to fuel injection? Unless you want to keep your ride 100 percent factory correct for seriously judged shows and such, we’d suggest jumping aboard the injection express.

These “self-tuning” systems offered by Edelbrock, FAST, Holley and MSD will have your ride always operating at peak efficiency without you needing to scrape knuckles and waste precious weekend time. And no worries about having that classic engine compartment ruined with something that looks like a Flux Capacitor, as these systems mimic the iconic look of a big four-barrel carb. So go ahead, put on that original chrome-lidded air cleaner with the engine call-out sticker on it, we won’t tell if you don’t.

Best of all, these state of the art systems make for a fairly simple, bolt-on proposition, essentially the same effort as swapping out carburetors minus the subsequent tuning. After you’ve bolted the system in place, you then enter basic information such as engine size and camshaft specs into a hand-held controller, which gives the system its base-line operating parameters. One twist of the key usually fires up your engine and then you’re smoothly off and running.

As you drive your car, the system’s ECU (Electronic Control Unit) continuously fine tunes itself according to information it picks up from the oxygen sensor. No more rough idling, no more cold-weather stumble. Indeed, according to this article in Hot Rod magazine it couldn’t be easier “No jets, no adjustments, no laptops—just bolt it on and turn the key.”

Cars of the world: Italy

Savory lasagna, creamy gelato, great artists and Sophia Loren are some of Italy’s greatest contributions to the world. But many would argue, especially we car buffs, that the best gift this boot-shaped country has kicked forth is a buffet of delicious automotive treats. Although great style has much to do with their appeal, Italy’s cars bring joy to the ear with their fantastic mechanical music along with joy to the enthusiast’s heart with their involving driving dynamics.

New or old, Italian cars are lusted after and enjoyed by enthusiasts everywhere. Whether one is cutting through traffic in a diminutive, old Fiat Cinquecento with sunroof open and opera blaring, or slicing through a mountain pass in a newer Ferrari 458 Spider with its top off and its V8 providing the soundtrack, grins are virtually assured for anyone within either.

To celebrate the irresistible cars of Italy, we’ve picked our favorites both old and new from the major manufacturers. Our choices come via a rather unscientific approach, yet one fully befitting Italy — they are based on pure emotion.

Alfa Romeo

1992 Alfa Romeo Spider

For a classic Alfa, it’s hard to beat the simply named Spider (which is essentially Italian for roadster). Available in the states from the mid-’60s to the mid-’90s, this affordable, Pininfarina styled roadster defined the Italian sports car experience. That is to say it looked sexy, sounded great and had its steering wheel laid down to almost a bus-like degree. It also meant it could be finicky and wasn’t the most reliable car on the road.

Alfa Romeo just came back to the states after leaving in the mid-’90s and offers but one model thus far. But what a firecracker the 4C is. With its snarly, popping, 237-horsepower turbocharged four, light (around 2,500 pound) curb weight and track-focused handling dynamics, this sports car is a blast to drive. It may be a bit harsh for daily driver duty, but the 4C, available in both coupe and Spider (removable targa top) body styles, makes no apologies for its “fun first” personality.

Ferrari

Ferrari 458 Spider

Choosing a favorite classic Ferrari is like trying to pick a favorite Beatles song. Nonetheless, we welcome the challenge and will go with an early ’60s 250 GT SWB (short wheelbase). Even those without 93 octane flowing through their veins would find it impossible to ignore this Ferrari’s handsome Pininfarina styling and incredibly melodic V12. Although these are priced in the millions (keep playing that Powerball), they are somewhat versatile, being able to serve as both a fairly comfortable grand touring car and a vintage racing track toy.

For a newer Ferrari, the 458 Spider pushes our buttons with its free-revving V8 engine cranking out nearly 600 hp while making all the right noises, open roof capability and of course the head-turning styling expected of the marque.

Fiat

Fiat 124 Spider

As with the Alfa, we’re with a classic roadster here, in this case the similarly-named Fiat Spider. Earlier versions (’67 to ’78) were actually called the 124 Sport Spider while the ’79 to ’82 versions were called the 2000 Spider. A Pininfarina design, the Fiat was powered by a double-overhead-cam, eight-valve inline four that grew in size from its initial 1.5 liters to 2.0 liters (hence the later “2000” designation.). A turbocharged version was also produced for ’81 and ’82. From ’83 through ’85, the car was marketed by Pininfarina as the Spider Azzura. Regardless of the year, the styling and driving experience are going to be similar, meaning those classic lines and the classic, arms-out Italian driving position.

Nowadays, not only has Fiat come back to the states, but they’ve brought the latest incarnation of the little 500 (“Cinquecento”) with them. Our choice is, no surprise, the feisty 500 Abarth, whose snappy turbocharged four makes us grin every time it crackles and pops when we downshift. Although it boasts a sport-tuned suspension that makes it a hoot on a curvy road, just don’t try to catch Miatas as its somewhat top-heavy feel and body sway when pushed harder show its athletic limits.

Lamborghini

Miura or Countach…Countach or Miura? We’ll probably change our minds tomorrow, but for now it’s the Countach. The official poster car of 10- to 20-year old American males during the mid-’80s, the outlandishly styled (by Gandini) Countach looked like a land-locked spaceship. Adding to the effect were the so-called scissor doors that swung upwards and made for a grand entrance or exit. A mid-mounted V12 with output ranging from about 375 to 455 hp provided the appropriate gusto.

For a newer Lambo, we’ll go with a Gallardo. Yes, it’s not as powerful as a Murcielago or Aventador, but we prefer its smaller, more easily managed dimensions and lighter weight. Besides, we could get by with just a V10 and its 500 or so horses. Now the question is just coupe or Spyder…coupe or Spyder?

Maserati

Maserati Quattroporte

Although Maserati made some great sports cars – Ghibli (the original sleek sports car, not the current sedan with the same name) and Bora to name just two – the company was also known for its grand touring coupes and sedans. Although the Quattroporte (“four-door” in Italian) has been produced off-and-on since 1963, we’re going to go with the third-generation version. Why? Because we’re Rocky fans and it’s what the Italian Stallion drove in 1982’s Rocky III. Fitted with a 4.9-liter V8, the Giugiaro-designed sedan put about 276 hp (respectable output back then) at the driver’s disposal. Fitted with plush, overstuffed seats and trimmed with gathered leather and real wood, the cabin of the Quattroporte was more business jet than road car.

Our modern Maser choice would be the GranTurismo convertible. Sporting Ferrari-sourced V8 power and a superbly detailed interior fit for four (provided the rear passengers are on the smaller side) the GranTurismo exudes class and power that are fully befitting a Maserati.

Wired Up: The Fundamentals of Spark Plug Wiring

Accel plug wires pictureNot all spark plug wires are created equal. And because moving electricity to the plug to produce a spark is so critically important, using the wrong wires for your vehicle, damaged wires, or poor-quality wires will undoubtedly lead to problems down the road.

As electricity travels along the plug wires toward the plug so it can generate a spark, it’s also looking to do something else – escape. The electricity is looking for any opportunity to jump from the wire and instead head down the path of least resistance. When it finds the escape route it’s been searching for – usually in the form of missing or damaged wire insulation – the results can include engine misfire, poor fuel mileage, hard starts, rough idles and lack of power. Electricity also generates radios waves and if it escapes from the plug wires can interfere with a vehicle’s radio and other electronics.

The plug wires’ insulation is what keeps the electricity from escaping, and high-quality wires will have more insulation that’s made from durable components that are better able to resist wear from vibration and heat. Over time, the engine’s heat cycling takes its toll on even the best spark plug wires, which is why replacement is recommended by many manufacturers at 100,000 miles.

There are primarily three types of spark plug wires:

1. Distributed resistance wires are constructed of fiberglass-impregnated carbon. Also known as carbon core wires, they were the standard on about 95 percent of vehicles before 1980.

2. A shift to inductance or mag (magnetic resistance) wires accompanied the rising popularity of Asian vehicles. Featuring a spiral wound core of a copper nickel alloy, the material presents less resistance to the electricity flow, meaning less current is needed to generate the spark, and at the same time the winding pattern and materials help prevent any Radio Frequency Interference (RFI) from escaping.

3. Lastly, there are fixed resistor wires. These are often found on European vehicles and feature steel or copper wire and a resistor inside the plug boot to control interference.

If you think your vehicle might be having some issues caused by faulty plug wires, begin the diagnosis with a close inspection of the wires’ condition. Examine them for heat-induced cracks or abrasions caused by rubbing against other parts. Look for areas where they’ve been burned through because of contact with an exhaust manifold. Also try examining the engine in the dark, looking for visible sparks where the electricity is escaping along the wires, and also listen for an electrical ticking sound, similar to what you hear when you receive a big static electricity shock. Also measure the wire’s resistance with an ohmmeter. One plug wire with a resistance that’s significantly different than the other wires could indicate that’s the problem wire.spark plug wire set photo

When installing new wires, make sure you’re using wires specified for your vehicle. Characteristics such as the wire length or a boot that attaches using clips as compared to a thread-on boot matter when it comes to performance. Also avoid problems by routing new wires in the same manner that the previous wires were, and removing and replacing the wires one at a time.

Using the best spark plug in the world won’t make any difference to your engine if that plug can’t get the electricity it needs, so choose and install plug wires wisely.
