good afternoon my name is ***** ***** ill see what I can do to help

first off is this gas or diesel?

what have you done so far? fuel filters, air cleaner, checked fuel flow?

Customer: replied 10 months ago.
Deisel new filters and fuel pump
Expert:  John Oliver replied 10 months ago.

as long as you have good fuel flow and pressure to the injection pump and the air filter is clean I would say you have an issue with either injection pump or injectors

that's me talking from my seat many miles away and not seeing or hearing what you have

it may be worth checking cylinder temps to see if you have a bad cylinder but the injection pump is in charge of the power delivery of the fuel
