i have a 1995 Pontiac Grand Prix with 100000 miles@Park, Neutral and Reverse my cars RPM is perfectly when my car is at a stand idling in bumper to bumper traffic my rpm drops to 500 and it feels as if its about to shut down then kicks back up to its normal operating rpm of 1000. I also notice when i move my steering wheel side to side the rpm fluctuates alot more or when i have my AC or Heat on. what in the world is going on please help is this serious should i fix it ?
if u have the ac on or other electrical equipment it will effect ur idle speed mainly when the ac cuts in adjust the idle speed slightly this is normal for it to do this when the electrical system is under load but u don't wont it to cut out so by adjusting the idle should compensate for this all so check ur plugs and leads replace if necessary
