I Have a 2009 Dodge Ram 1500. I replaced the spark plugs and ignition coils in February 2019 because I would get a random P0300 code every once in a while and it was fine for about 8 months. I'll clear the code and it will be fine for a few months then it comes back. I did one of those autozone head gasket leak tests and no leak. What could it be? Happened twice since September.

Unfortunately there are over two dozen reasons that code can trip. Try my video fixing random misfire po300 Scotty on YouTube
