Pontiac Problems? Ask a Mechanic for Answers ASAP
Hello, my name is***** oil pump and alternator both turn with the engine so if idle is going low that means both of those components will be turning too slow. The common problem to cause low idle is a dirty throttle body. When throttle body gets dirty it will cause airflow restriction during closed throttle conditions such as idle, slowing down, or starting. This will eventually cause low idle, stalling, and hard starting. The fix is to get throttle body cleaner from your local parts store, spray onto a rag, then wipe out good. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
