I know this is a common issue, but the causes vary. I had this happen to me before and it was due to my IACV [PITA getting to], and another time I just need a tune-up. I recently changed my plugs, fuel filter and for a brief time things were good, but now its getting bad. There will be times I come to a stop and the RPMs are fluctuating between 500 & 1000. This also happens when I come to park my car and roll up my windows. Maybe my alternator is bad? I just replaced my battery and immediately afterwards the idling was dipping below 500. Any suggestions?
