    yeap..sticky IAC or could have something to do with you never bringing it over for me to look at that throttle body too. Pick up a can of TB cleaner and come over one afternoon.

    Unclip it, remove the two 10mm screws, flip 'er over and spray the shyt outta the sensor. I used MAF sensor cleaner on my sensor, it was covered in dust and so were the walls of the whole thing
