And sometimes it's located right under the well by the steering wheel(like in my car). Many dealerships or if you have an Autozone in your area, will do a code read for free. If your manual does not have the list of codes, you can also type them into Google, and it will tell you what each code means.
I use to have a '96 Deville that had the code reader built into it. You'd just have to push a series of buttons on the console(it was one of those that had everything electronic-the odometer, the gas, MPH, etc). & it would return the codes right there, no code reader needed., coolest thing ever

Naw dude, you'll be surprise at what you can accomplish on your own. If you put a little effort into it, you'll be able to fix it. As for the check engine light, they have these electronic devices that you can buy at the store. Its a bit expensive, but well worth it. Its called a code reader.
Anyhow, you have to know where to plug the code reader (that's the electronic device that gives you the numeric codes). Sometimes, its located in the glove compartment, sometimes its located in the coins department. There are even cars that have them in the trunk. Your owners manual will give you the location of it. Okay, so, plug the code reader in, and it will give you numeric codes.
From there, it will give you the OBD codes. These codes give you specific reasons as to why your car check engine light is on. Some cars will have a label of OBD codes behind the glove compartment. However, your cars manual also has it. For example, it will say that its spark plugs. From there, all it takes is a few tools and you can do it on your own.
I'll definitely advise anyone to buy their own code reader, because sometimes all it needs is a simple fix. Mechanics will charge you several hundred dollars just to check your code read and do some few simple adjustments.
