Default 2001 IAC valve humming problem

Basically, I am getting this loud humming sound from the IAC valve that is blowing the noise into the CAI tube and causing a huge noise and irritation. Best to just watch the video... More info on the Youtube write-up...

Fixed!!! Problem started after I got the car back from having the engine overhauled. The mechanic put the IAC valve on flipped around. The bolts and gasket are symmetrical, so it fits! The plug should point towards the center of the car and not towards the passenger side!!
