Hi there. The P0302 trouble code is an indication that cylinder 2 is misfiring and is not getting the necessary spark to its spark plug. You might want to read this article as it will indicate the common causes of this code, and possible solutions to resolve this issue. The P0300 will trigger as a default code anytime the random misfire is found on any of the cylinders.
