Hello Guys and Girls.
I have a 3.9 v8i that revs extremely high at startup once the car is warm. The stepper motor then kicks in and slowly brings the revs down to normal.
I have changed: Stepper, TPS, both water temp sensors and the fuel temp sensor so far.
The flow meter works, but cannot set the CO below 4. I have tried, but cannot get the base idle to 525rpm. The butterfly is set correctly.
