Hello All, wanted to runs something by you all to see if I am on track with my diagnoses with my idle issues. Engine is a B16A2, The engine idle bounces up and down, I have already set the TPS to 4.88 at rest, checked for vacuum leaks around the intake manifold with negative results. if i remove the intake and place my finger over the hole in the throttle body, upper right the idle smooths out to normal. once removal of my finger the idle returns back to bouncing around. Am I safe to say the problem is the IAC?
