this damn truck...
i was driving around town stop and go and shutting truck off and on running in stores. i ran into a store and when i went to leave the truck had no power. wouldnt boost or smoke at full throttle and would only go 10mph. shut the truck off and started back and truck was perfect. i went about my day and everything was fine. the next day my cel came on and truck went into limp mode. codes p0069 and p2262. cleared the codes and truck ran fine for about 50 miles. then the same sequence happened. i did a little research and looked at three sensors 2 at the turbo air intake on the motor and one behind the fuel cooler on driver side valve cover that had a tube running in where the egr bolts up to the exhaust. this motor and these sensors have less than 3k miles. the sensors looked fine. i sprayed some carb cleaner in them and cleaned them. what else should i look for? i have deleted the dpf already so i cant take to dealer for warranty unless i return back to stock. like i said, fresh motor and i know its a sensor somewhere just dont know which one. and i put my gauges to barometer and it red 14, my boost was never negative at idle and it functioned properly even when truck was acting up, fuel pressure was always up and back pressure was usually double the boost when accelerating and would function a little higher than boost when cruise.
