My 2004 powerstroke 6.0 liter just started running ruff When you first start it and run down the raod it caughs and sputters once its been ran for a while it will smooth out and run good. I've changed the fuel filters and the air filter. Most of the codes come back to the injector module I have 1001600 miles on it

Item 10, in the link below, may help:
