I think I found my problem
I had a brain storm this evening about a injector test trick a caterpillar tech showed me once and thought I would try it this evening it involves taking a non-contact infrared thermometer and checking each manifold port at idle " you have to do it quick before the manifold gets a hot all over" and the colder the engine the more time you have I have Two ports that are about 40-50 degrees diffrent than the other six. 2 and 5 are colder on mine no codes so I'm guessing stickage?

you maybe on to something and I have heard of others doing the same kinda thing with a thermal gun
Dont know how well it works
What would be cool is if you could backup your findings with the thermal Gun with a cylinder balance test
or change those 2 injectors and see if it helps your problem but could be Ficm related now that I think about it or Injector harness

Step 1 of this procedure is in-line with your theory. I wouldn't go beyond step 1 because of the damage it would cause to your injectors running without fuel.
A cylinder balance test could be used to possibly confirm your findings...

My plans are to do a oil change saterday and put the rev-x to her and see if that helps they say it's a mirical oil then I'll send her to ford Monday for the injector balance test if the rev-x don't help her

That was the exact path I took... I tried RevX and moved to a 5w-40 synthetic. It helped smooth things out, but I ultimately had to replace my injectors. The dealer did diagnostics and gave me the results - that was hugely beneficial.

If i can get it running Better And get alittle more time out of the injectors mainly till i can get alittle more cash to change them ill be happy i know rhey normally start and go one at a time I've always use 15-40 rotella in all the diesels I've owned but I think I'm going to motorcraft this change and add the rev-x to each change if it is what I've heard everyone say it is also going to change the thermostat while I'm at it

I live 20 minutes from their store and did just that. Also picked up my HPOP from them recently for about $550. pensacoladiesel.com
Cheaper if you pay shipping rather than sales tax (if you pick up).
