IAC Screw size This is going to sound crazy, but does anyone know the thread size of the IAC screw in the throttle body? I have a ruined screw that I'm not even sure I can get out and was thinking I could just find a screw with the right thread size to replace it with. I called the dealer and they don't carry the screw unless you order a whole new IAC.
go to your local junk yard and pick up a couple of them (in case you mess up another or lose one). The same IAC is used on a huge line of gm vehicles... just match one up and you're good to go on the screws.
