truck has been getting progressively worse. So I had a cylinder cut out test done today. All cylinders checked ok and all injectors were within 2-3 points(whatever it is) of each other. Here is the problem. Truck vibrates/misses/stutters under acceleration or pull. Smooths out if I let off the go pedal. So that's why I thought injector instead of driveline. I need ideas here. Injector harness? No codes were logged either. I am stumped. It also vibrates when the jakes are engaged. And I also have a ticking only when the jakes are engages at lower rpms. Please help!

Bit of INFO would be helpful such as Model of Truck and Engine
-
Have you checked you charge air, and/or EGR...

Run over/head and CK. back

sorry bout that. 2005 w900 with c15 cat mxs. have not checked charge air. no egr. I was thinking overhead but my fuel mileage has only fell off a couple tenths, which may not matter. I have put 340000 on it since I bought it and I have not had the overhead run.

Nobody has any suggestions?

Had sort of a problem like that on a T600 with a cummins and was ok after injector harness was changed, was almost like it was flooding under acceleration
-
This one is not smoking or anything. Just seems to.run like crap loaded or pulling a hill.
-
Mine did the same best way to describe it was that it FELT like it was flooding whenever it had to pull a bit harder
-
I would have the overhead adjustment done ASAP. 340,000 miles it's way past due IMO. When was it last done by the previous owner? Some people think it's overkill but I have it done every 100k. Had it done a couple of weeks ago. Cheap insurance. They might find something broken in there.
