I have recently acquired the dreaded dead pedal. I had my truck scanned for codes a few hours before, and came up with 2 MAP sensor codes, one being voltage to high, the other voltage too low. The first thing that came into my mind, was the VP44. I cracked the #1 injector line at the head and found fuel shooting out with great velocity. I gather that this eliminates a failed VP44. MY question is, Can a map sensor cause dead peddle?
