Just bought a 2004.5 3500 6 speed. It has a banks intercooler in it and banks exhaust but no chip. Drove home from Houston, Tx to Jersey Shore, PA with out issue. However it now intermittently idles rough and sometimes stalls after it first starts. I havent noticed any other side effect yet. Any ideas on where to start???? I have 98.5 2500 with a 24 valve, but am learning the common rail cummins is a differnt creature.
First things first, see if you have any stored codes. With the key off and out, get in and close the door. Put the key in and cycle it on-off-on-off-on (leaving it on) and watch the odometer. It will start with "---------" and then read off any codes, finally saying "done".
You say you haven't noticed any other side effect, so I'll guess that includes no white smoke.
Check your oil, see if you smell diesel, put a few drops on a paper napkin and let it sit for a bit. There will be a lighter color "halo" around the oil spot after a little while if there's fuel in the oil.
I'm sure you know that part from your prior experiences though.
Things that can cause surges and rough idle and stalls right after starting are usually fuel-related, so we need to find out if you're getting good fuel pressure and rail pressure. If you're having a high or low pressure situation the codes will probably tell us.

So i did some investigation and found that the High Ram Intake was leaking right at the manifold. Called Banks and ordered new gaskets. Then decided to check the bolts. No more than hand tight. So after tighting the intak down the truck runnes remarkably better but stil shoing the same code. Also found to two wires run up from the undersde of the fuse box out of a harness and into the fuse box. they are twisted together and taped. Cleaned them and used a connecter. Any idea on what that might be?????
