Injector Driver Module (IDM) maybe? I don't know nearly as much about 7.3's as most of the people on this forum, but those were the symptoms mine had when my IDM went out.

What is your fuel pressure? Is it a miss or just rough running? How bad was your old fuel filter? Did you clean the little screen in the fuel bowl while in there?
