What does it mean when the check engine light comes on??
It means that there is a malfunction with the engine control system which is most likely related to the emission control system, the computer stores some diagnostic trouble codes that should be retrieved, the trouble code numbers will help to find where the problem may be. The way to get the trouble codes is by putting a jumper wire in the diagnostic connector under the hood between the terminals TE1 and E1 with the key on the check engine light will blink the code, for example a code 24 would be two blinks followed by four and so on. Once the codes are known you can reply back to me and I can help further.
