[QUOTE="scott degroot, post: 796854, member: 66039"] The reason behind this is that when you are on the gas the IAC is taken out of the picture, even if the IAC were to mysteriously slam shut while you were accelerating the amount of air that it introduces into the motor is negligible. Realistically the only thing the IAC does is create a calibrated vacum leak to make the engine rpm go up or down and when you are on the gas vacum leaks are of no concern being that almost all of the engine vacum is lost during accel anyways. Why cleaning your IAC cured your hesitation while going up a steep hill while obviouosly under moderate to heavy acceleration is beyond me becasue it just doesn't make any sense at all, maybe you cleaned your maf and a few other things at the same time along with a so called pcm reset...IDK. Heck I can take the IAC off and not have any of the problems here that people say have been cured by cleaning or replacng the IAC. I know engines and there control systems can throw you for a lop once in a while but with the amount of odd problems here that have been solved with IAC's I would have thought that i would have stumbled upon one or 2 of them in my day.
