P0300 is a huge pain in the ***. It's way too general, so it does no good as a DTC. My tuner ended up turning it off since my flywheel rattled enough for the ECU to think I was misfiring.
When my car is stopped and idling I hear a rattle maybe that’s my flywheel rattling and could be causing the misfire?
