My truck sputters and runs extremely rough. It never dies. This problem has been going on since July. I have replaced 2 injectors, fuel module, engine harness and pic harness. It drives good for a few weeks after repair and goes right back to the same symptoms. I would appreciate any help. I am not a mechanic. I am just trying to get some help so I can use the truck longer than a few weeks at a time. I have a video to share but can’t upload it here.

Any codes?
Your going to need to get use some more information. We need balance rates, main rate, desired MPa, Actual MPa, missed cam & crank counts, Maf and Map readings. And maybe even timing at idle
Is the engine tuned? Lift pump?

Since you are not a mechanic, I would get the truck to a competent Duramax shop to get it looked it.
Can I ask your location? Maybe we can recommend someone.

Springfield Missouri. I have a mechanic that has made the initial repairs. I am taking it back to him but just thought someone might have a similar experience. Everytime I pick it up it tests out good and runs good for a few weeks.
If you don't have the equipment to diagnose or even just get us the information it's going to be really hard for anyone here to provide any meaningful help. So, as tom said. Best to take it back to the shop. Or maybe another shop who might be better at finding the root cause
So are there any codes showing when the engine starts sputtering? That would help a lot.
I wonder if Corbin is still running his shop? He was in West Plains.

There is no service engine light. Sorry to not have a lot of information. I wish I could upload the video which may help explain the issue a little more.
