There might not actually be a misfire. P0300 is a catch all code when the ecu gets confused. It can be 1000 different things triggering it. When it was cold, I would get it because the flywheel would rattle and trick the ecu into thinking there was a misfire. I ended up having the code turned off. There are codes for the misfires of the individual cylinders, so it hasn't been an issue.
