Wiped Cam? Seems to be often enough in my experience.

Could pull valve cover and use a micrometer on valves to see how far they open and close and compare to one cylinder that does not misfire.

Pulled valve cover checked travel all looks good hard to measure up and down measurements no real way to put micrometer on rocker or valve spring keeps walking ? But travel looks good

I checked the logs and it doesn?t seem like the car is going into power enrichment ? The commanded lambda stays at 1 through out the pull why is that?

Not a tuner I’m a Ford heavy line tech I pay to have my tuning done
So to answer your ? I don’t have a clue could that be the problem ?

I'm having this exact same issue and cant pin down the problem. Did you ever get it figured out?

Cylinder 3 acted up first. Then at the end cylinder 7 started misfiring.

You need to swap ignition parts and re test drive. Put coil from 3 on cylinder 1. Plug three on cylinder 2 wire 3 on cylinder 4. Straight swap. Mark them if you need or take notes.
Do the same for cylinder 7 using parts from cylinder 5, 6, and 8.
Do another log and see if you have movement.
