They reflashed the ECM and replaced the coils and plugs. No charge. I'll get it back next week. We shall see.

CrazyR, how'd you "clean out" the old injectors? Did you have them sent in somewhere?
And are you referring to the injector o-rings when you say seals?
Franklin Jones, I used a small length rubber hose the same diameter of the top of the injector with a clamp, different sized heat shrink tubing, a can of carb cleaner, alligator clips wire and a 9 volt battery.
I attached one end to the injector and the heat shrink tubing to attach to the end of the hose from the can. Attach the red and black alligator clips to the battery and the injector to open it then spray carb cleaner straight through it. It cleaned each one out and the spray pattern looked the way it’s supposed to when I was done. And yes I meant the O-rings.

An Injector can be leaking, emptying the fuel pressure. When the vehicle sits the fuel leaks out into the cylinder. If the cylinder is flooded it may not fire causing a misfire. You can have white smoke at start up. None of that would cause a code unless the misfire was bad enough.

FINALLY an Update. Ford reflashed the PCM, put in new plugs and replaced the Coil BOOTS not the whole coil. Started up instantly runs better. Before I was very aware of the transmission shifting or so it felt. It may have been misfires. Everything is running well.
