driving down the road the other day! and truck started to almost studder for power. no check engine light. then the other day i went out to start it in the morning and engine light was on. so i scanned it and said boost sensor high voltage. the same code i got when i bought map sensor less than 6 months ago. but it acts differently than it did the first time when the map went out. the first time it was just dead pedal i could hardly get up to speed but now it will get up to speed but its like the engine isnt getting fuel constantly?

 

possable lift pump issue
or maybe air in the fuel system.

 

Do you have a tuner on your truck, if so, what kind?
