Acceleration problem

[Adamfigge]

I bought a 2000 f350 with the 7.3l diesel in it a few months ago with 119,000 miles on the truck. I drove it for around 8,000 miles and started having a problem when accelerating. When the truck is pulling itsself either on flat ground or up a hill or whatever, just as long as you have to accelerate, you get to about half throttle and the truck starts to shake, kind of like it is running out of fuel, but if you push the pedal to the floor it will power through it or if you back out of the throttle a bit it stops as well. I had a mechanic look at it and they can't figure out what may be causing it, and don't want to just start throwing parts and money at the problem. So far the computer was changed because we thought the chip may be causing it, so unplugged the chip and it erased the computer, changed the electronic pedal, changed the oil thinking it may be foaming, and checked the injector harnesses and can't figure it out. I don't know very much about trucks, but I have to get this figured out and would appreciate any input or thoughts. Thanks Adam

fuel filter maybe? Otherwise take it to a ford dealer you trust they will know right away.

i would start with fuel filter and i am a tech. could be lots of things. fuel, inj, ect. was the filter replaced?

There were two ford mechanics working on the truck. The fuel filter was replaced at a quick change place and it started not long after that. They replaced it with one of the ones with a built in cap, so I thought it may be that as well so I went and bought the filter and cap from ford and that didn't help. The water in fuel light is on, but the tech said he checked and there is no water anywhere, he just thinks the sensor is messed up?

NEVER let quick change places work on you truck... Did they drain the bowel
before they changed the filter? I bet they just pulled it out and let the
nasty stuff float around and then put in the new filter allowing the dirt to
get to the injectors.
