Hey peoples, just wondering why you need to adjust the IAC valve pintle to 28mm? Wont it just re-adjust itself? i mean it moves up and down anyways till it finds where the car is idling normally, if the pintle is too far out wont it just pull itself back down to a normal range? Last time i had mine out i didnt adjust the pintle and when i whacked it back in, the car revved heaps high for a while then it slowly settled back to normal now the car starts fine, idles okay. Has this buggered up the range that the pintle can move? is a different voltage to control pintle position now required to obtain normal idle and possibly making my ecu think something it shouldn't? Should i go and actually pull it out and adjust it for any reason? Cheers, Apoc.
