2005 dodge 2500 cummins stalls at idle
Hey, all. My truck runs perfect when cruising over about 1000 rpms. But when idling it will randomly stall out or start running very rough. It always does it in the morning when it's cold, though. I already had the fuel filter changed, injectors cleaned, and the air charge temperature sensor changed. The truck has 130,000 thousand on it.

stevemartin, I'm having the same issue. Only first thing in the morning when its cold. Did you ever get this fixed?

cerberus60, could the FCA really cause this type of issue? What is the theory behind running oil in with the fuel?
dangerous1965, I thought injector as well so I did an injector return flow test and a pump return flow test. Both passed... Any suggestions?
Thanks!

The tests don't rule out a cracke dinjector tip, just the wear in them.A bad tip can give the same symptoms but they never go away.
The FCA sticking will cause a rough idle and dying at an idle. The ULSD has been over refined to remove the sulphur and that has dried it out. The FCA's are picky about lubrication for good operation. The oil in the tank adds back needed lube.
