    newbie with an LB7 problem

    I have a 2001 LB7 truck (150,000 miles) I have been having issues with, hopefully someone can help. The truck was hesitating and stuttering when I rolled into the throttle. Changed fuel filter - nothing. I took the truck to a diesel guy and he tested the whole fuel system and said it was...
