Update: I checked the harness and plugs that I could. Couldn't quite make a definite difference when any one plug was pulled at idle. I will have a tech put a Snap-On scanner this afternoon and check to explain the 4 DTCs my ScanGuage is reporting....
I checked it a few weeks back when I changed the oil (among other things at the time) I did drive it home, reluctantly, and made it fine. It never got worse anyway. It has not smoked at all so I decided to take the chance. During that drive I did run it in Tow /Haul mode because it didn't go ito 6th gear and that is where the shaking is the worst. I will check it today.
Just ran some diagnostic tests and they showed the #7 injector is out of balance. However it also showed that the #7 injector also failed the buzz test to. So there may actually be something wrong with the harness or connector. Will be digging into this later tonite. If anyone has any other suggestions, please chime in.
No I don't have it yet. Heck I haven't had her on the road longer than a week since October! The boss (wife) says its time to ditch her! Not sure if she'll ever be confident enough to take her on the road again. Now that I am starting to have issues w/ injectors, I ain't sure what to do.... after I replace the #7 injector.

You probably got a contribution/balance code for #7 which means the injector or cylinder is not contributing the same as the other 7. If it's a wire there are low/high wiring codes that would/should indicate wiring.
Well I have remedied my injector woes for now. Although replacing #7 fixed my engine, my concern for dependability while on the road was still waining. So I reluctantly, although excitedly, traded for an 2011 F-250 with the 6.7l. I only say reluctantly because I loved my '05, had her decked out just the way I wanted. But I here the 6.7 is a great engine for power and reliability. Thanks again for everyones help lately!
