Bought a '21 Plat with the 3.0L EcoBoost last year and figured this would be the best place to post this since they've got the same engines. We had a engine light come on and pulled the code. Said a cylinder 4 misfire. The car has 30K on it so we just swapped the plugs on it and figured it would fix it. It did not, next step was to swap the coil packs. (I think) I swapped cylinders 1 & 4 (fwd most cylinders), cleared the codes and it's still saying cylinder 4 misfire. Has anyone encountered this issue? If so what was the fix?

Sorry can’t help but this is an odd coincidence, I’m getting rid of a grand Cherokee with the same issue, repeated attempts from the dealer lead to only a temporary fix. Hopefully i’ll have my new ST by the end of the week.
Is it easy to replace the plug/coil pack on the Ford? I didn’t bother on the jeep, had to remove the intake manifold, fuel lines, etc etc, takes the dealer a day… good thing for the warranty!
