You didn't tell me the year of your car so I don't know if you have an OBDI or II.

Just pull the code and see what the trouble code is.

And your next questions is "How do I pull the code."

If you search that question all will be revealed.

assumming the car is OBD1, you can check it by putting a paperclip and connecting port E1 to TE1. If you do a search for "Check engine light" there are a few threads that show you how to read the CEL using this method.

If its OBDII, then take it to AutoZone, they do diagnostic checks for OBDII cars for no charge.
