My son's friend brought over his 95 gt he just bought with an idling prob. Earlyer today when they went to pick it up My son called and told me that the mas air was unpluged, the seller said it wouldnt idle with it pluged in. I told him to plug it back in before driving it up here. Well this after noon when they showed up I started to go at reseting the base idle an re adjust tps to .98 incase it wasnt done after the egr delet that had ben done. It idle's great now , but has no power right off idle and through rev's and some time's backfire's. What the heck? re checked timming, and fuel pres. still no luck. Unplug mas air and it rev's great , Anyone know what's up?

i know there touchy, if the air aint hitting it at the right angle they can run like sh*t
