Any time the truck has been setting long enough for it to cool off when I start it it runs rough and if I don't let it set and warm up it has very little power and it shutters if I try to accelerate to quickly. I had it in the shop a while back and had the injectors checked, I had one bad and thought that was the problem after replacing the injector it still runs rough. While it was at the shop they also thought I needed to have my turbo cleaned I hadn't heard of having this done just wondering if is something I should consider?

I am having the same prob... only he described it better than I did in my thread

Burn it!! You are about to have more problems than you think. I have 20 in my fleet and wish they woud all disappear every morning I come in to work. Let me tell you what your problem is because I have 4 that had this same issue ready!!

1. heads need to be replaced.
2. EGR cooler and oil cooler needs replaced
3. Injectors, all of them, will go bad not matter what pre-maint. Program you have.

I have a direct line into ford corporate at this time due to my threat of a law suit fot this motor. Again, I have 20 of them so trust me when I tell you get rid of it now.
