[QUOTE="Zeb, post: 1528565, member: 30304"] I think you have your ICP and IPR numbers turned around. IPR should be listed as a %, and ICP as psi. It sounds like you are losing ICP signal and then it switches to the default setting which will make them idle rough because default ICP is higher than necessary for normal idling. Is there oil in the ICP sensor plug, and on the pigtail? If there is, that is most likely your problem. Also see if you have a P2285 code which is lose of ICP signal. If you find any/all of this, replace the ICP sensor with a Motorcraft ICP sensor for an 05+, and at a minimum clean the pigtail (brake cleaner, air, and then a dab of dielectric grease). [/QUOTE]
