6.0 Runs rough when engine warm

Hello everyone! I just want to start off by thanking everyone for all the valuable information I have found on this website. I am a new F250 6.0 owner and I had no idea what I was getting into. I love the truck, but have apparently purchased a neglected 6.0. With that said....I have recently done a coolant flush, oil change and filter change. I have added hot shots secret with no help, then turned to rev-x. I have searched high and low on the discussions looking for a similar issue to mine and haven't found one. My engine will start up fine....everything is smooth and sounds like all cylinders are firing. When the engine gets to temp, it seems like one or more of my injectors will start to miss. It will run that way until it sits and gets cool, then the same process. I have tested the FICM and I get over 48v. I have a sneaky suspicion that maybe one of the resistors within is lifting when it gets hot enough. Anyone ever heard of this problem? I just think it is weird. Sometimes when I start the engine, it will puff light black smoke while running rough (for about 15 sec), then everything will smooth out like it was clearing it's throat. I appreciate the help!! (sorry for the long post)

I dont think you needed 2 threads on the same topic did you? You need to get a monitor first off. Second, Test your injectors. Do you check for codes while its doing it?

two threads?

Hello....sorry....I wasn't aware that I had posted two threads....I thought I was just posting the one. I have not yet pulled the codes. A monitor is next on my ever growing list of things to purchase. To test the injectors, should I just take it to a Ford dealership? I understand they are usually the only ones with that type of diagnostic ability.
