Injector?
I have a 2004 F250 early build over 260K miles on it. After taking a trip out west Texas and back I noticed my truck starts to jerk a lot around the 50 to 60 mph range under moderate throttle. Getting a contribution code on #6. FICM voltage stays over 47v during KOEO and startup. Took an inferred thermometer and even after truck is at operating temp #6 is reading about 3 degrees cooler then the others. When cranking the engine everything sounds smooth but startups are getting harder. Usually let it idle for a few minutes before taking off on cold start but I am having to let it warm up longer before I can get any power. Did a bubble test and passed and oil level hasnt changed. Fuel mileage has been sucking bad also. Safe to assume the injector is shot and needs replaced? Use Delo 5W-40 Syn every change with motorcraft filters.

I fought biting the bullet and replacing my #4 for two years. Spent a whole lot on Hot Shots, Seafoam, Arch Oil, and T6 oil changes mean time. Put a dumb $250 rebuild injector from O'Reilly in today......what the heck took me so long? Love my truck again...enough to wax it!
