2.0 TS GTV Idle speed adjustment......
I cleaned my throttle body (really needed it) taped up the air ducting between the body and the MAF (some cracking and a small hole) and checked the idle control stepper (on the side of the throttle body). Is that the same as the idle control valve that people speak about? Now the car idles a bit high at 1,000 rpm. I did notice as part of the throttle body assembly there is a screw on the cam near the return spring. It makes sense that having cleaned the crud out of the body that there would be increased airflow at very small throttle openings, so should I just back the screw off a fraction to bring the idle down or is it all managed electronically?
