Default Surging at Idle

Hey guy's - trying to help my neighbor with his 95 C4, over the last few weeks at idle it starts to surg a little, you can just touch the gas pedal and it right back on track. We checked all of the intake fitting, pulled them apart and tightened them back up-No change, went around all of the intake manifold bolts and they are all tight, looked for any loose vacuum lines and they all seemed fine. ANY suggestions as to what or where to look next.

Pull the IAC to see what IT looks like. Chances are, the IAC and the IAC passages in the TB need a good cleaning.

RACE ON!!!
