2003 6.0 hesitating

First post on the forum
Have a 2003 F-350 which has been a great truck so far except...recently, when cruising between 1500-1900 RPM, in OD, no load, the engine hesitates, kind of a herky-jerky action. If it were a gasser; I would say that a plug is fowled. I have been told that the EGR may be sticking. It never did it until I started driving it everyday since my S-10 has some issues (chevy....). Was also told that since it has been a daily driver for 3 weeks or so, that things are getting coked up. I just need some direction. This being my first diesel, I am not sure what the best course of action is. Thank you for any help

Sounds like an ICP sensor/harness problem. When the ICP harness gets oil soaked it can cause a surging issue. The only way to know would be to look at the ICP voltage while it's acting up.

how can you do that

ICP, EGR, turbo sticking.

Could have a bad injector.

Take it out and run the *** off of it and see if it smokes black out the back.

Yeah I do baby it and I heard that when you don't drive it like it's stolen every now and then the EGR will get gunked up. I appreciate all the input gentlemen!

Yeah, run the hell out of it, constantly.

Being nice to these trucks is almost the worst thing you can do.

I change the most turbos/egr valves on trucks that get driven short trips...grocery store, back and forth to church, quick trips, etc, you know?

And trucks that tend to idle a lot will wet stack more than a truck that doesn't.

If your truck idles a lot, make sure you put a fast idle switch on it, using the SEIC (stationary elevated idle control) provided with the factory engine management system.
