Ford Explorer 2024 Misfire Problems

Ford Explorer 2024 Misfire Problems. I'm currently getting random misfires only on the bank 1 (firewall) side of my 2016 ford explorer 3.7l. First sign is a few seconds of roughness on cold start that.

That it came back pointing to #4 again, after plugs, injectors, and even a coil swap, makes me wonder. The code indicated cylinder 4, and i hadnt replaced coils.
