Thanks for the pic! So just to be sure, I'm only spraying the throttle body spray cleaner on the cone shape piece at the end only and where the IAC is mounted? I thought you said not to remove the rubber O-ring because it would readjust the position. Also, the IAC plastic housing is the entire black piece attached to the cone shape piece right? If so, can I just wipe it off with a clean cloth?

You're welcome. Correct plus the pintle and spring area below the cone shaped piece. Also, do not diassemble any part of the IAC or use force by moving or turning the pintle. On the cone shaped part even after spraying you will most likely need to rub the carbon off with a rag. Remove o-ring before using the spray cleaner and re-insert after cleaning and IAC is dry before re-mounting.

Also, spray some PB Blaster or WD40 on the two Torx T20 screws holding the IAC to the throttle body before attempting removal. GM uses thread locker. Sometimes they break off but make sure you turn counterclockwise. Good luck!
