Hello and welcome! My name isCustomerand I can assist you with your question. I take it your looking for some possible causes? Has anything been replaced up to this point for this code?

Thank you for that information. When was the last time the engine had a full tune up? The most common cause for this code and misfire condition are bad spark plugs and ignition coil(s). We see this all of the time in the shop. I would start there, clear the codes and take the vehicle for a nice long drive to see if the code comes back. Chances are that will do the trick. If not, then I would suspect a fuel delivery issue (plugged or leaking fuel injector on number 1 cylinder).
