You also didn't mention whether your oil cooler was changed. EGR cooler and oil cooler are two different things. It is the oil cooler that will cause the wrench light, for Low Oil Cooler Efficiency.

loss of power 6.0 F550 powerstroke 2006
Continuing on with this thread, we took truck into dealer while traveling thru Colorado and they put new turbo and CAM (not sure what this is) and truck seemed to run fine with not much loss of power until 2500 miles in and while climbing a not too high hill the truck was not able to go past 20 to 25 mph. It eventually kicked into power and worked fine for another 600 or 700 miles. We took into dealer in Nashville for fuel filter change and oil change that was due and the next day we had loss of power on residential street (no hill) and could not get past 20 to 25 mph. Pulled into shopping center and lifted the hood, idled up the engine for about 5 minutes and then it was working fine. We are getting ready to continue on our trip (another 1500 to 2000 miles before home) and wonder what can be causing this problem. Any help would be appreciated. After spending $2500 for the turbo and cam, it is frustrating.
