Hi Guys, I always look here first when I have questions. This place is great. The dead pedal?? My truck started with an intermintent (sp) lack of power, that and a Check Engine light. I findly checked codes today. Here is my laundry list of codes; P0234, P0236, P0238, P1291. P0234 = over Boost. P236=Turbo boost out of range. P238= boost high. I would guess my MAP sensor is in need of replacement. The engine will pick up RPMs and drive around town OK, but just no boost. I will get a new sensor tomorrow. Would that be a dealer part or Napa part?? Any Ideas would be great, Thanks Mark
