At that mileage you should also clean your throttle body. And the MAF if the 5.0 still has one; I'm not sure as I haven't looked under the hood of a current-gen 5.0. The 3.5 Ecoboost is speed density tuned so it doesn't have a MAF.

2017 f150 Platinum, hummmmm. You have either a 3.5 Eco or a 5.0 V8. I believe in that year F150 both motors were Direct Injection (DI) only fueled motors. Your issue COULD be carbon build up/fouling on intake valves causing misfire when COLD.

He’s never changed the spark plugs. 🤦♂️
IF you try to quote his “spoiler spoiler “ it shows his answer. Not sure why he hid it that way. And he has a 5.0
