P0302 means a misfire and it can be due to spark plugs, wires and the injetors. something was not working correctly and it sems the problem has righted itself thus no more indictor light but the code would still be recorded in the engine computer.

Misfires are sometimes difficult to diagnose as there are too many possibilities.
