Ok, fellas here is a doozie for ya! 1997 3500 4x4 with the ever popular 6.5. with 195500 miles
I changed the injecters with dieselcare.com performance marine diesel fuel injector nozzles. I had a few leaking injecters but i fixed that, then i had a leaking heater element in the fuel filter housing, and fixed that, then i had a lot of jerking and crap going on so i relocated the PMD with a new one, i sill had a small fuel leak so i pulled the intake and changed rubber hoses. i don't see a leak so i think i got it licked! BUT.......now whe i give it full throttle i get the slight jerking like it's not getting enough fuel but only during WOT or when it's under a load. I have installed a new vacuum line to the wastegate, new fuel filter, new injecter nozzles. Any ideas as what it might be?????????????????????????????????? -

get a fuel pressure gauge and see what your running. it might be the fuel tank sock is full of crap and needs to be cleaned out. its possible your lift pump is going out. ill give you more info tommorow but im going to bed. btw who makes the injectors you put in. -
