If it were more wiring related though wouldn?t it be doing it all the time instead of only after the car runs for a while? On cold starts I can rev it to anything and it never does this but drive around for 5-10 minutes and any high rev will cause it to only fire on cylinder 4. I’m going to check the signal from the ecu and igniter to make sure that is still going through.
