missing bad
 

ok heres the deal, i have a 6.5 with the electric pump. ia am a cummins guy so i know very minimal about the 6.5. the problem is when the truck is at idle it runs smooth. as you start to drive it does good then it begins to spit and sputter and feels like its gonna die. then is clears up and runs fine. i dont think its a bad injector because it doesnt miss at an idle. like i said im a 12v cummins guy.

check fuel filter if have some water in there it will do that check and clean all the at back right side of motor that where computer grounds are at also check the LP and the OPS not knowing what yr is OBD1 OPS run the LP OBD2 don't run off the LP also right where computer grounds are there are ground straps under A?C dryer one goes to back of the head and one to frame make sure there are good the 6.5 count on good grounds

alright sounds like a good start. thanks for the input. i will let you know what i find out.

Oh check PMD ground on the top IP make it clean and tight
