ISC is new from mitsubishi. Only a few months old. Wandering rpms are self resolving but I am getting a little random rpm surge when stopped in gear post MAF replacement. Vibration is still a problem still rough in gear at operating temp. Something is not telling the engine to lean out? Or increase rpms? While in gear at a stop. Its almost backwards meaning out of gear no ac rpms increase and idle is smooth in gear w or w/o ac rpms increase a little but not enough? And I get a steady shake through the steering wheel - shake stops as soon as i'm out of gear. Is throttle position sensor a possibility?
