Pipeline22

I'm the fourth owner of the pickup so who knows what it's been through. She is almost damn near new now with all the upgrading and and updates to it. I'm very particular about my stuff so any little hiccup or malfunction I'm looking into it. Hopefully this helps others out. Like I mentioned in my first post, I've seen this problem on a lot of other forums but no definite answer. Thanks everyone for the input.

Put a rebuilt head on my truck and it quit idling rough once it warms up. Looks like one of the valves in #1 had a bad seat. Valve sucked up a little. Haven't torn the old head down to check for sure as the truck runs perfect now!

Just unplugged my comp box to see if it was causing the problem.. Picked up a few codes P0237 already ordered a new sensor from Genos Garage. The other was P0602 control module programming error.

I have a little OCD so it drives me crazy knowing that there is something "wrong" with the pick up and I can't figure out how to fix it?

No, at least it would give me a staring point.

My 02 cummins 2500 4x4 with nv4500 has a rough idle or like a miss after the truck is warmed up. It smooths out if the AC kicks in or you let the clutch out just a little as if you were to roll ahead a bit. The truck has a new vp44, TPS, and FASS titanium pump. I've seen this problem posted on other forums but nobody had a fix to the rough idle. Anyone have this problem or have a fix for it? Any help would be greatful.
