would an ill fitted exhaust system cause fluctuating idle? I'm only wondering this because I've exhausted (lol) every other logical solution such as tps, aac, corrosion, etc. One stop light the idle is 1100rpm, next is 900rpm and the rpms take a while to come down from a gear. Perhaps the turbulence is causing the pistons to not be consistent...lol...damn, i dunno.
