Ok so you are saying that it maybe the compression and not the injector? Even though the buzz is very dull in sound, on the buzz test?
I will try to find someone that has a compression tester for these trucks. I have just about had it with this truck, I am looking for a 7.3L that is newer so that I get more info from the scanner, than I do with the E99 systems.

I had left a bit of a resolution on the service ticket that Troy started, but have yet to hear back about it. If you can leave this thread open for a bit, I'd like to hear back from him myself.

Cody,
I have replaced the #7 and #8 injectors, but to no avail, I still have the problem. It don't seem to be as prominent, but still has the miss. I am in the process of going back through every check that everyone suggested prior to replacing the injectors. Does anyone know what this motor should have for compression, and what is acceptable? I am about ready to buy a bow tie, if I cant figure this out.

We need to get you down here for a weekend and see what's going on with your truck.

you are a long way away from me. Otherwise I would get it to you, to figure out.
I am looking at a different truck, that way I don't have these problems.

Troy,
You need AT LEAST 340 PSI while the engine is luke warm. A HEALTHY engine will usually be in the 370-400+ PSI range. Anything lower will usually cause a miss until the engine warms up or the boost comes up a little bit. Low compression will usually be accompanied by white smoke from the exhaust that burns your eyeballs if you stick your face in it.
