dont over tighten the IAC valve...it breaks off easily, and youll spend an hour , like i just did, trying to figure out how the hell to get the broke piece out of the threads , stuck inside the throttle body, i got it out "thank ***" but it almost cost me a tbi unit....heh....so heed the warning, just snug it down.....

 

15 lb-ft, or 180 lb-in is the recommended torque. just had mine out to clean off all the crud, and that worked fine.
