7.3 power stroke problems.

I have a 2000 F350 7.3 with a 6 speed manual transition. I just replaced my injectors and now it is idaling rough at 750 rpm but will jump to 1100-1200 rpm. when driving and idling it sounds like its missing. what could it be?

this could be quite a few things
i would check fuel pressure, oil pressure
could be a bad cps.
if their is oil coming through your icp sensor change it.
make sure the under valve cover harness is hooked up right and connections are tight.

Go under the truck and disconnect the fuel pump wiring. Then pull both the small fuel lines going to the heads off from the fuel filter housing. Crank the engine and one of the lines should start pumping pressure off. Trace the line to whichever head and this is the side that the injector is messed up on. You will then have to pull all the injectors to figure out which one it is. You will probably be fine with just replacing the orings on that one injector.
