Really Need Help!!!!!
I have a 2005 Dodge 3/4 ton 4x4 Cummins. My truck runs great but once in awhile it will knock puff some smoke and then its fine and it mostly does it when i shift through the gears and start hittin the gas pedal. It doesn do anything when Im just cruisin along. Anyone got some answer for me?

It sounds like you got an injector hanging up...knocking and smoking is a classic sign. A black fuel filter is normal, they just get that way...Baldwin is about the best filtration you can get for an OE replacement (5u IIRC).
I would first try two things...run a heavy dose of Power Service Diesel Kleen through it, I'd probably do a large jug in a tank of fuel. And then try using some 2-cycle oil (search for the kinds on this forum) after the Power Service to see if that helps. You may either have a really dirty injector, or one that is just going to fail...sometimes dosing them real good helps.
Keep an eye on your oil level...make sure its not mysteriously gaining oil.

One thing that puzzles me is that it only happens between gears...almost like the APPS is doing something weird?
