trying to figure out what's wrong with my truck

Starts and runs just fine, has an intermittent miss between 1500 and 2200 rpms. It kinda cuts out then picks up like somehow I instantly added a cylinder or two? It started and died twice trying to leave from work. Ran rough intermittently all the way home. I replaced fuel filter old was wasn't that dirty. Replaced cps. What should I look at next. It's been at a diesel shop for over a week and they keep telling me they are too busy to have a look. Any idea's would be appreciated. I might bring it home if it will make it.

Check the valve cover harnesses above and below the valve cover. They like to burn up. My did the same thing your describing when mine burnt awhile back til finally it stopped running

Agreed. That is the first place I would check. I would also have it scanned for codes.

The shop tested everything and said they couldn't find anything wrong. They test drove it twice and said it runs great. Then they said my water in fuel light came on and wouldn't go off. They couldn't tell me if the mechanic drained the fuel bowl or not. This was the second shop it was at and neither shop checked for water in the fuel. I drove to my friends house and we drained the fuel bow and found a lot of water and murky looking fuel. What's the easiest way to remove this? Should I pull the tank? it's the front tank. Or will siphoning and new fuel be OK? Thanks everyone.

Make sure you clean your fpr screen and I would also recommend running some diesel clean or similar through the system

I cleaned the fpr screen a couple of weeks ago. How often should this be done? I also have been draining the water out every time I drive it. I add diesel clean or some diesel additive to every tank. Is there an additional water seperator/fuel filter I can add inline somewhere to help with catching more water that is easier/cheaper to clean/change? Thanks everyone

Might also want to try filling up at a different station sounds like they might have a water in fuel problem

E-Fuel. The filters and water separators are now on the frame rail and a lot bigger.
