Check engine light


Recommended Posts

Could somebody give me a genereal list of what causes the check engine soon light to come on. It goes off once in a while for a bit, but comes back on. 2000 Cutlass, 3100. Thanks.

Sorry, my mistake, it's not my car. 2000 Buick Century, still a 3100 though.

There could be very many reasons. Go have it scanned at a nearby auto store for engine codes and let us know what you get. You should be able to get it done for free just about anywhere.

Get me the codes and I will post up the diagnostic steps from Mitchell On-Demand
