I installed a Granetelli throttle body following instructions carefully and I keep getting irratic idle and engine/wrench light.

I adjusted the "butterflies" slightly less open than the stock ones and have adjusted the stop 5 times 1/16 of a turn increments, clearing error code each time and still get engine light and high idle speeds.

Anyone adjust one of these with success??????? What am I doing wrong?

Found problem. Spring had become disengaged from tangs in motor cap. Re-engaged plastic tangs FULLY by removing small plastic access cover after re-tensioning the spring. Hope this helps others with this tricky adjustment.
