Ok this car is driving me nuts. i did the IAC restrictor mod to eliminate rev hang... That ****ed up my idle forcing it to idle at 1500rpm I removed the IAC restrictor got a new tune from my tuner to make my car idle lower than 1000rpms. It now idles perfect at 750rpms and rev hangs like a *****. Ill come out of a gear and it will just sit at 2000rpms until i rev the car. What on earth needs to be done? TPS replaced? IAC? I adjusted my TB idle screw which i didnt want to do so i might try to put that back where it was.
