2001 xlt bucking

[doomdrv01]

I am very worried my dealer is giving me the run around!
I have just purchased a 2001 Explorer 4X4 XLT 4.0 SOHC with 17,000 kms on it. It is awesome except for the following:
Between 45 and 70 kms/hr, when you are driving on smooth pavement, and not accelerating or deccelerating, the truck bucks - like its trying to shift gears every few seconds. The outside temp is freezing or a little below with low humidity.
The dealership's mechanic rules out the 4X4 cut over and says the engine is not the problem - running smooth as glass. He also says all the Ford's do it. He has registered the problem with Ford but holds out little hope. He has updated the PCM.
Any similar experiences or suggestions?

Try a new dealer..if they are giving you problams and not fixing it find someone new. We have been known to drive our vehicles to a dealer 45 minutes from our home just because we had a better experiance there. You should not have to do anything to a truck that is still under factory warentee. Just try other dealers (Even maybe Lincoln/Mercury dealers) until one of them actually puts forth the time to narrow down your problem.
Good luck and welcome to the site!

Mine started bucking like that right before the tranny went out, yikes!

BTW, not all fords do that, that's total BS.
