NEXT,... WHAT INCOMPETENT MORON? TOLD YOU THAT THE TURBO IS BAD JUST BECAUSE IT "coughs" (cummins calls it "turbo chuff")?. That turbo is going to do that if the egine is getting bad feedback data to the intake and/or EGR. DId you replace the EGR Delta-P sensor and clean out the passages in the mounting block? That will cause it, the IMAP sensor can cause it (replace it!), and the exhaust back-pressure sensor, and as well, the EGR valve not positioning correctly will too.


Also, ensure you have the right program in the ECM, and that it is up to date, and read this post carefully ...

I PM"d you my number.

Yes the dpf filter reset option was performed, as well as the doc reset option (both)

Actually did the reset twice.

I cleaned the egr valve myself and it wasnt stuck, the imap, egr diff psi sensor and exhaust back psi sensor as well as the differential pressure sensor on the dpf was replaced.

Ports were cleaned out, "blown out" "sucked out"

The egr side was in fact sooty but it should be...

Could kenworth have made a mistake with passing a failed dpf filter to me???

We had a truck do a similar issue and I said "fu k it" and replaced the dpf with a new filter after the previous filter was "cleaned by kenworth" and that truck has not thrown any issues since...

Gotta keep in mind these trucks are so abused by the long idle times.

We have a few trucks with more hours then miles do to long idle times in the oil fields.
