1 Answer

P0316 Misfire detection monitor

P0300 Random misfire

P0302 Misfire number 2 cylinder

When you get a misfire this is a cylinder that is not contributing, this can be from ignition to injector to even a vacuum leak, Because you have P0300 this is not only random misfire but also means more than 2 cylinders, start looking for vacuum leaks especially at the EGR valve, and PCV valve, also check the sparkplug wire especially inside the sparkplug well for water intrusion.
