Ok I was having a surging issue I took the IAC off cleaned it really good noticed it didn't have a gasket ordered one re-installed the IAC..I disconnected the Bat for about an Hour I also re-adjusted my TPS car seems to idle better but now I have this LOUD whistle from the intake...if I rest my foot on the Gas pedal it goes away...it still has a slight surge on Re-start even stalled one time...The car has a 70 mm BBK TB on it I have no EGR im usung a spacer with an EGR block off plate...Im wondering whats wrong NOW?.....
