[QUOTE="TurboM700, post: 63880, member: 59"] Not saying this is the case here but the mid 2000 year Ford tauras had the same issue and it end up being whent he AC was one it would change the 5v ref to the MAF sensor causing it to think it had more air going thru it and this would cause a rich condition along many other things. Its been a while since I have worked on a 6.4 so I cant say if they even have MAF sensors. I know the 6.0l do and thats mostly what I work on. It was an easy check with the vehicle running and up to temp. Read the MAF value on the scan tool and see if it changes with the AC on or off. Do this both idleing and going down the road.
