Answer 1

P0300 Random misfire

There is a lot of factor that will set a random misfire and when the misfire event occurs, clear the code since the engine runs great, If the CK ENG LT comes on and it is a P0300 look at the freeze frame to determine when the misfire took place, such as the temperature or at warm operating temperature and what load. this will help determine what is or ever is causing a misfire condition.
