Hey guys, I have an odd problem that only happens occasionally, once and a while if I'm cruising or whatever at say 2,000 rpm and I push in the clutch the engine will stay at 2,000 rpm until the transmission forces the idle down, at which point it will stick to whatever the rpm range is then. If I restart the car it immediately fixes the problem. Anyone have any idea what could be causing this? IAC perhaps? The problem is that it does it so rarely I cant really get it to do it when I want in order to properly diagnose it.
