Hey Scotty, love all your videos and now I’m having an issue with my Ford I wanted to ask about. I bought the car recently and of course a month in a P0306 code appears which is a misfire in cylinder 6. So I swapped the number 5 coil with 6 and it was still misfiring and The code came back for the same cylinder two weeks later. Checked the spark plug as well and it was fine. So I’m stuck. I have done research and apparently this has happened a lot to Ford edges where the PCM goes out and you have to repair or replace the PCM to fix the misfire. Which is very expensive.. thanks in advance for the help
maybe it's a fuel injector.
have a look at our misfire topic in the FAQ
If research dictates that it be the case, unfortunately more often then not it is. That being said, have you checked the coil wiring? I've seen in some cars they rub off causing misfire. If nothing there and the spark plug was gapped right, since you already did a coil swap, it would be that pesky pcm...
