    well its simple just time consuming... the iac is on the bottom of you TB. there is a harness for it on the left side.. dissconnect that. then you take you intake off so that you can dissconnect the TB from you intake manifold. In order to do that there are 4 bolts in the 4 corners... then there are 3 vaccum lines on top, you have to be real careful not to break them.. once you get your TB off there are i think 5 or 6 screws that holds the iac on. Hit them with some pb blaster and let it sit... then spray it again and repeat.... they strip very easy... once you get them off the iac will come off. there will be a gasket on the TB remove it and replace it with the new one put the new iac on and put everything back together..

    Where the hell is the IAC in this thing?
    Took out the throttle body but I can't find the IAC.
    Please point it out to me?

    Lol the iac is the big bulky bottom half with the electrical connector. Also I hope you have a tool along the lines of an impact driver, those screws are a bitch and will strip insanely easily.
