I have a 2002 truck with 54000 miles on it. Last week I took the truck in because it had no power at times,, you would step on the throttle and it would bog down as if it was not getting fuel. . The dealership replaced the lift pump - no pressure, then said the problem was fixed,, I drove it home and it was still doing the same thing still,, but not as bad,, I used a code scanner and there is a P0216 code set on the computer. . however the engine light is not on. The truck is back in the dealership right now,, I took the technician for a ride but I could not get the truck to do it while the technician was in the truck. . SUGGESTIONS?????????????????????? HELP :{
