Everyone has heard it a thousand times - BUT IT IS TRUE!! A car with a group of parts that compliment each other will run better than a car with a mismatch of parts. This group of parts is called the combination. This article is designed to help you build the perfect combination. A well thought-out combination will not only make your car more enjoyable but also enhance the drivability and acceleration.

When I first bought my 'Stang I always had problems with the idle. No matter what I did it always went up and down, up and down, up....uh, you get the point. After performing a full tune up, which included changing the spark plugs, plug wires, fuel filter, air filter (k&n), cap, rotor, and setting the timing and tps voltage I was disappointed to find that the car still had a lousy idle. So what's next? Try changing the idle air bypass solenoid (IAB)? I was about to, until I noticed that the throttle plate in the Throttle body was so dirty that you could barely see the edges of the plate.

Although this may seem very basic to many people, some people don't even know the easy way to check fuses. I've seen people suffer through the big pain of taking each and every fuse out one at a time to see if any of them are burnt. There's a lot easier way of checking fuses without taking them out.

Ever notice that fuses have two small metal "tabs" on top of them? Those "tabs" or prongs are for checking them with a tester. You can buy a specific tester for this task but an ordinary 12V tester will work.

First things first. You'll need a few things: a timing light, a distributor wrench or a ratchet and socket that will fit the distributor hold down bolt, and a little know how.

Whenever you change the rear end gears to another ratio (e.g. 2.73's to 4.10's) you have to change the speedometer gear too. Why? Because when you change the rear end gears you also change the ratio between how fast the speedo gear is spinning and how fast the car is actually going.

Here is a chart to figure out which speedometer gear you will need.

The PCV valve does exactly what it's name suggests, it provides "Positive Crankcase Ventilation". So if the pcv valve gets clogged then it won't provide proper crankcase ventilation which can cause numerous problems including: severe oil leaks, damaged gaskets, and excessive emissions.

Now that you know why you should change it at every "tune up", we're going to show you where it's located.

Ever look closely at that clear plastic cover over your gauges? If you look close you'll notice that there are tons of very fine scratches on it, which dull its look. Have you ever gotten dash cleaner/polish on that plastic? I did, and the cleaner stained the plastic. No matter how much I scrubbed I couldn't get the stains off of the plastic.

There are kits that you can buy which include some type of polish to get those scratches out, but why spend money when you probably have everything you need to polish your gauge cover already?

Upgrading the TB is one of the popular mods that any Cobra owner will think of.

Back in May of 97, after all the long hours spent researching what I should do to my car, I decided on getting a S-Trim for myself.
