    when i start my car the idle is kinda rough and then out of nowhere the idle starts to climb to about 1k then drop to like 5 then up then down and then it cuts out. could it be my IAC? or even the MAF? i cant test anything tonight because i ripped my throttle body gasket and i cant get one until tomorrow

    If you can't test anything today, then we really can't help you right now.

    Seems that you already have an idea of what the problem may be, so do some trouble shooting and see where that gets you.

    i have my old throttle body and i tryed swapping over the iac and other components over and it turns out the iac was bad but the car was still playing up. tomorrow if it still does the same thing after i put the gasket on im going to unplug the maf to see how the car reacts.

    If you have a bad gasket..you have a self induced vacuum leak.
    I drink..so consider that when reading my posts.

    When the gasket was bad.. was it bad in the area that would let coolant into the motor?
