04, 6.0 F250 Powerstroke.....

After truck is warm I will "Bog down" when i go to accelerate from a stop. Almost as though its shifted to a 5th gear. (Im not thinking its actually shifting to 5th gear but thats the best way to describe how it feels.) Then it will regain power and run totally normal. It only happens randomly but seems to happen only when warmed up. I've also notice while driving, if i let off the gas it goes to a very low idle and once i go to get back on the gas it bogs down (again this only happens randomly)... Very frustrating. I no longer trust pulling out in front of traffic at a cross section.

Ford could not duplicate the problem because they did not drive it enough, even though they said they did..... Although they ran full tests and found nothing wrong with the EGR valve, turbo vains, or injectors. Im still thinking its an EGR problem...... Any ideas? Please!!

 

I am having this same issue. did you ever figure it out?
Thanks!
