When I put ,y foot in it fast my engine starting sputtering real bad but if I let outta it it's fine I just haft to realy ease into it any idea on what it is I was guessing
Lift pump and praying it's not my injection pump

 

Kinda sounds like timing to me, or gov springs messed up

 

Ok I'm draping it off monday to the diesel shop just trying to figure out how broke I'm gonna be

 

Anybody else got any guess
