Any number of problems can cause the Check Engine light to illuminate. Your best bet is to find a mechanic who can read the codes and tell you what the specific problem is. Shop around, though, because the cost of having a mechanic do this can be anywhere from $15 to over $100. It's a simple procedure, but like anything, if they have a corner on the market they can change anything they want. Or you can do it yourself...it's easy. You can purchase your own code reader through your local auto parts store or on line. I've seen OBD II code readers for as little as $50 on line. The OBD II will work on most post 1996 cars, but not all, so make sure the reader you buy will work on your particular car. Good luck.
