Check the IAC first, you can take it off and clean it with WD-40 or any other cleaner that wiull not har the rubber seal inside of it. Then I would check to make sure the TPS is @ .95v, either one of those could cause a condition like that.

Sounds like once it goes into closed loop, it acts up.

Maybe 02 sensors?

the IAC is new, TPS i dont know if I can adjust it or no, caise mine is non-adjutable (94 mustang).

sounds like when it goes into closed loop it starts to act up. Does it run OK does it kinda hesitate some? or pop? how long has it been doing this? if it has always done it since the MODS you might need that lil AIR adjuster from FMS that goes between the IAC an TB those work pretty good actually
