Running bad after warm up
2004 Ford F-250 Base 5.4 v8 f250 145000 miles
Once the truck warms up and put in drive it will barely run. If you're in park you can Rev it up and it's fine. I've replaced plugs, coils, fuel filter, air filter, and injectors. I also drained the old gas as it had been sitting, washed and dried the tank completely and refilled with new. I checked the fuel pump and it runs perfectly fine but I'm stumped.

I have the same issue with mine. 5.4 triton also. Don’t find you can drive it find at a lower rpm and as soon as you try to accelerate rapidly and it downshifts that it basically bogs out and loses all power? I replaced all those things in mine also, besides injectors or fuel pump. Im also pretty stumped on this issue
