What would cause smoke under the hood of my' 02 grand prix se after changing the alternator. Also, the rpm jumps to 4 then goes back down over and over.
Something isn't right, open the hood to determine where the smoke is coming from and what is burning. Might be related to the alternator work.
Be specific .. does it smell like burning ... is it more of a vapor? Why was the alternator changed. Did that solve the problem ,, How long has it been since the alternator was changed? I suspect (like Tom) something related to the alternator is the problem. DO NOT RUN THE ENGINE LONGER THEN REQUIRED TO DETERMINE THE SOURCE Better yet ... don't run it at all until you have a mechanic look at it
