I have a 2014 ford f150 fx4 4x4 5.0 V8 automatic 6 speed. My problem that I am having is that I have a misfire that I have not been able to diagnose. P0308 P0305 and P0300 did all new plugs coils injectors intake gaskets new vvt solenoids and nothing is helping. The truck will run better but not perfect when. I put in brand new plugs but only for 10 minutes. It misses at idle, drives fine and accelerates with no problem. If I let the truck sit and idle for 15 minutes the misfire almost completely goes away until I drive it and stop then it comes back. I have no clue what to do.
Look up the firing range for that engine. You might have mixed up the ignition coils on the wrong cylinder by accident.
They are all in the right spots, the plugs that go to the coils are in a lume and can't reach any others.
Your vehicle may be in for a tune-up. I would also check the fuel injection system.
All new injectors coils and plugs have been done less then 2 thousand miles ago, pump is testing good not sure what else could be wrong
