Hundreds of things could cause the check engine light to come on as with any car. To determine what the problem is you must use an OBD II code scanner. Autozone or some other diy parts stores will do this for you for free.AnswerAlways check the Gas cap to make sure it on tight. A loose gas cap can cause this to happen. AnswerIt's either a faulty catayltic (sp) converter (We have a 2001 Impala and have had to have a new one installed twice), a faulty oxygen sensor or the gas cap (either not screwed on just right or, being 7 years old, the gas cap is not sealing correctly and you need a new cap. Good luck. AnswerOn my 2000 Impala, the Exhaust Gas Recirculation Valve has required replacement about every two years. This causes the check engine light to come on. A sure way to determine if the EGR is At Fault is to drive from a cold start, go for 10-15 minutes at 50MPH, and then coast to a stop. If the check engine light comes on during decelleration, the EGR is faulty - this is a GM test protocol for this vehicle. The EGR's function is to recirculate exhaust gases back into the engine for reburning, and if it is not working properly it can lead to poor fuel economy or failing emissions tests.
here is a really common problem and fix. start your car andOpen up your hood and take some carb cleaner and spray it on all the rubber hoses you see in your hood. Carb cleaner evaporates so dont worry about messing anything up, and if you here your engine idle up then you have a vacuum leak and this is a very common problem.
