Are these problems related

My 06 F250 seems to be giving me a few problems, I was just wondering if these are related? 145K on the truck. 100% stock.

Runs rough when cold. I go out and start it every morning, it starts right up no matter how cold it is outside, and idles perfect within a few seconds. I let it idle for about ten minutes before driving. When I pull out of my neighborhood, the truck feels like it is missing and is very sluggish for the first three to five minutes. After that she runs well. I have noticed however that it still feels like it is missing on light or moderate acceleration. If I really get on it once it is warm, no problems, accelerates quickly and without any miss or hesitation.

I tested the FICM when cold with a Scanner 48+ volts. Injectors passed the buzz test when cold and warm, egr valve has been cleaned, fuel filters new, oil and oil filter changed, air filter changed. No codes current or pending.

When yours was acting up, did it just seem as if it didn't want to move unless you really got on it? If I mash it to the floor, the turbo spools up and the truck accelerates quickly and will do this from a stop or at just about any speed. If I try to leave a red light with light or moderate throttle, it just feels like it is missing. The turbo sounds like it always has, it holds plenty of boost and I don't see my tach jumping, it just does not accelerate smooth during light acceleration, feels like it is struggling. No smoke, not even on start up on a cold morning, like I have read that many others experience.

Mine was doing same thing. Dealer changed IDM as they were once called, or FICM. Also changed the EGR valve. Said number 6 injector was sticking a little on startup. That cleared up within a few days.
