The 1997 Saturn SL1 that I drive, usually the Service Engine soon light comes on & stays on for quite sometime & then after a while it goes off. I've said this before but according to our mechanic he said don't worry about it. What should I do, any suggestions?

That is a response you get from a mechanic when he has no idea how to fix the problem.
The "check engine" light is an indicator for a system that monitors many electronic functions in the system, also called the "malfunction indicator
lamp" (MIL). It can come on for any of hundreds of different causes from any of the systems that the computer monitors. Some are very important
and can lead to further component or engine damage and some are emissions related not as serious but still a problem and need to be repaired.
Your first step is to have the computer scanned to retrieve the trouble codes that were set when the check engine light came on. Those codes will
give you specific information about what the computer saw and will get you pointed in the right direction to find your problem. With a 1996 or newer
and some 95 cars and you have an AutoZone or Advanced auto parts in your area, they will read them for free. Once you have these code numbers, we
can be a lot more specific about what your problem may be.
