mustard is on a distinguished road

Stock 2003 5.9 4x4 64k miles with the same issues here. Truck starts up perfectly, then when it starts to warm up in the driveway it will stumble. Even if I immediately drive it, it will drive fine for a few hundred feet, then the engine will stumble and occasionally misfire. Once the truck is allowed to sit and warm up further, the issue goes away and the truck runs great. No check engine light either.

Changed the air filter and I added fuel injector cleaner to a brand new tank of fuel, no luck. Next step is plugs, wires, cap, rotor. We'll see..

Any other thoughts?
