Hey all, lets start with the important info:
Year of truck: 2004

Motor: 6.0 Powerstroke

Mods: EGR Delete, Superchips Tuner Performance MOD, new oil cooler.

Anything you've done recently: I have just replaced #1 and #2 Injectors, removed and cleaned IPR and EGR since my problem has started

How is the truck primarily used: Typically drive 28 mile round trip back and forth to work.
Some driving to kids events and grocery store.
When did the issue start, and if it's intermittent or all the time: Last Tuesday night I was driving to my dads outside of Birmingham, just got on the interstate and reached 75 miles per hour. I heard something like it was spraying near the fire wall and the truck began bucking/surging. I found I left the TPS unplugged at some point, but plugged it in and thought that was my issue, I also pulled the IPR and cleaned it and reinserted it. Then tonight on the way home tonight I got on the interstate and about 3 miles down the road it started again. Once under 60 mph or so, truck runs great. I dont get it.

Anything else that might pertain to the issues at hand: I have researched this and find multiple suggestions for repair but really dont want to throw sensors at it when it could be something completely off topic.

Any codes, and what are you reading codes with: I believe the code thrown was P2285 Injector Control Pressure Circuit Low, I will try to repeat to enure code.

Any suggestions are greatly appreciated and I will post final results from each suggestion.

 

so there's a couple things that will cause this..
1) icp sensor failing.
2) ebp sensor failing.
3) overdrive clutches and direct clutchs failing.

whats your tranny temps at when this is happing?
whats icp volts, ebp volts and vgt percentage while this is happing?
