I have read through the many helpful postings ... and think i have narrowed down my problem (i think) ... Here are my symptoms: truck cranks fine, idles fine, when reving up it hesitates and jumps, when putting in gear (manual) and pulling a slight hill it gets very sluggish and jumping smokes a little, when i turn it off i smell a little un burnt deisel in the exhaust pipe and surrounding air, when driving down hill and not pushing the pedal very much i can achieve speed. When on slight hill going up it slows and starts jumping and missing (i finally got it home) ... i checked the oil level, it is not completely full but not low enough that i would see to cause hpop problems. It has never stalled on me. My first thought was clogged fuel filter or water contamination. After reading through posting i think it may be the uvc harnesses.

Im just a shade tree mechanic and this is my first deisel. What would be the first thing i should check ... im broke.
