2019 F150 3.5EcoBoost... EVERY morning within the first 3-5 miles I get an average of 200 misfires verified using Forscan live data - (Cyl6, and yes I swapped coils and the misfire remains at #6) Looks like a fuel injector, however, after 5 miles or so it completely clears up. The remainder of the day runs fine with no misfires. Ironically a Ford Dealership replaced Inj#6 a month ago so I am bringing it back. The question is why does it remedy itself after 5 miles? Some connection heating up/expanding?
What does the lowest circle tell you?
Does it say Injector >>>open circuit?
.
Its electrical.
Is electrical plugged up solid?
Is there a wire issue?
Good luck.
