Got an 03 F250 6.0, just bought the truck. Truck has low power and smoke blue when accelerated. Ran scanner on it, no codes, injectors all seem to be fine, egr funtions, vgt function, ficm voltage is at 48.5volts. Checked fuel filter and it is clean. Cannot get truck to rev over 2000rpm no matter what. Anyone have any ideas what this could be?
