Ive read a couple threads about this issue, just trying to pin point the problem. I recently installed some 75hp nozzles, the truck drove awesome for about a week. Then it started hesitating a little during acceleration but didnt loose alot of power. last week i was getting hard on it and egt's went high (almost 1500) wasnt sure how high, and the trucked just backed off. Then the cel light came on. Threw the P0193 code with the P0628 went to autozone and cleared em. Did the same thing today... Ran it hard until egt's got up.. it backed off... CEL light came on... Same two codes... Took it to get diagnosed and the local diesel shop said that it could be the edge juice w/a thats causing the hesitation or it could be an injector. As far as the codes i dont know whats making em come on Diagnostic's checked out good. Ive been reading about a fuel rail pressure sensor, checked into it and i think mine took a ****?? i think? I popped the bolt off the sensor and it had fuel around it. Any other opinions about my problem?? Thanks!

Possible sensor here is diag procedure for that code. Good Luck
