Thanks for all the help guys. I'm 4 hours from KC. I talked to the service writer. Its going back tomorrow and I told them they are on the hook for my rental. My gauges show good ICP, FICM voltage and everything else is normal. If I had to guess, I think the injector they used went bad already. My FICM is pretty new. I'll update when I find something probably Monday.

Update!!!!
I took it back Saturday morning. They stepped up on the rental until they figured it out. The funny thing is that I got about 1/4 mile from the dealer Saturday and it smoothed out and started running right. The code was still there though. So they kept it for 2 days and couldn't find anything wrong except the code would come back every time they reset it. So today they tore it down and replaced the #2 injector. They tech said it bench tested good and he could not find any shorts of chafing in the wiring harness. So they said they replaced it and I finally picked it up this afternoon. Seems fine now but I am skeptical. I haven't hooked up my reader yet to see if I have any codes. By the way, it wasn't really $2300. I had the fuel filters and oil changed while it was there. The only other thing I can think of is that I replaced the pass side battery the day after I picked it up and then the next day it started running bad again.

The code is P0266-powertrain cylinder 2 contribution/balance. Right it is Motorcraft. I guess its possible that the injector just went bad and they will replace it. I can't get them to call me back so I am just showing up in the morning and demanding a rental and another injector. Has anyone seen injectors go bad this soon, less than 2 months, before? I assume it is possible that I just got another bad injector. I do everything right, oil change every 5k at Ford, fuel filters every 10k also at Ford. I have always used Diesel Kleen and had no problems till now.

I don't know about fuel pressure. I only monitor ICP and it has looked normal. The miss is intermittent. It missed real bad this morning then smoothed out. Then the next time I drove it it was smooth then started missing really bad after driving a while. I just did a short run for dinner and it wasn't missing until I got almost home. It makes me believe there is a short somewhere, or is that how an injector behaves when it is starting to fail? The bad thing is, all 8 were replaced at 59k just before the warranty ended. Now it has 121k.

You need to get a fuel pressure gauge and check it. The PCM doesn't read fuel pressure. Low fuel pressure can cause injector issues also. 59K miles for a whole set of injectors is, IMHO, is very abnormal. If it had a short it would throw a different code. Something is very strange.

I agree. But shouldn't they have checked the fuel pressure when they couldn't figure out why the code was showing up but the truck wasn't mising the second time I took it in. They said the injector "bench tested" good. But they replaced it anyway and that appeared to solve the problem. Could fuel pressure also be imtermittent?

I think your Battery/Alternator Problem Killed the FICM Again
Your Voltage at Idle is WAY WAY LOW!!
@ 12.2 volts that's Not enough to even Fulley charge the Batteries
If you cant figure any other Cause and the FICM is Bad send it to ED www.ficmrepair.com
the problem with Ford FICM is they haven't upgraded the electronical parts inside from what I understand and ED Puts Top of the Line Parts in it
I wouldn't be Surprised if this truck Needs New Batteries, Alternator (Get a High Output if you Do) and FICM
Check that FICM Cold before and At Startup
Then Check it again at WOT up a Hill or something
