I know that it does it at heavy loss of vacuum but this is only at like a little above 1/4 throttle. There is also a miss only when the A/C is on. I replaced the IAC yesterday, helped smooth the idle and ceased the stalling bu the miss is still there. When the air conditioning is off it runs like a champ. The miss isn't constant when the A/C is on though so that is kinda confusing
its only sometimes. Mainly at idle.
