Can't find it. I think it was D, but they were saying how hard it is to keep the high RPM on the Fords.
Ahh Asspopper. Very easy. Two person job. Sit in car. Rev up to@ 1800. Have person #2 pull plug to IAC motor. Light will not set. Now 2250 to 2750. Do test. Come back down SLOW Have helper plug back in IAC. Bring to idle.
That is how you do the Ford's that will not stay at the needed speed. Take the IAC out of the system.
Sorry to you that I have not offended. Give me time. I will get to you.
