Kam Posted July 8 Report Share Posted July 8 Hi, Replaced the oem Subaru N14 throttle body with the bigger IAG Bosch 82mm one, Tuned the engine, everything runs great except that idle speed is high about 2000rpm and I can't seem to close the throttle angle less than 1% The only thing that was left to do is to set the idle ignition timing to -10 Degrees to lower the idle speed to 1100-1200rpm but i feel the coolant overheating... Do you have a correct calibration for this throttle body ? Thanks Kam Quote Link to comment Share on other sites More sharing options...
Vaughan Posted July 8 Report Share Posted July 8 I would recommend visually inspecting the throttle while it is at 1% to see if it is fully shut, if so this would suggest you have an air leak causing the high idle. Quote Link to comment Share on other sites More sharing options...
