Searched, need idle hep, car idles high.

Followed FSM, every single sensor,switch, plug, plate, screw...you get the point has been checked and is within spec.

car still idles at over 1300 rpm.

wtf.

jspec s5 block, s4 manifolds and sensors, s4 harness modded to fit s5, vac rack intact, s4 afm - level, s4 ecu.

is it possible that the previous owner of the car had drilled out the tb plates to compensate for...porting perhaps?

anybody have any ideas before i take a sledge hammer to the car. Thanks.
