Default Adjusting Throttle Pos. Sensor
I was wondering if someone knows how to adjust the base idle the 4.6 v8 gt. I just installed an accufab plenum, 70mm throttle body, and airraid spacer and it idles kind of high around. Should this befixed or is this normal just because of the bigger volme of air coming into the engine.
Thanks.

If theres no idle set screw on the the throttle body you either have to adjust your tps sensor or have it addressed in a tune

Idle should be set at 750 rpm. There should be a set screw on the left side of the throttle body. The tps sensor should be self set and doesn't get adjustment
