All I can say is that the car used to idle evenly at about 700rpm. Now it will idle there and then dip 200rpm for a second or two speed up to 750-800 then settle back down for 10-30 seconds and repeat. THIS IS NOT NORMAL. Since I am getting no more help from the dealership or Ford I plan on cleaning the throttle body once I get the special cleaner from ford and see if that helps. Next will be replacement of the MAF sensor. If that doesn't do it I will research the stepper motor or what ever else I can find for suggestions.
