What does the P0300 code on an engine mean?
The P0300 code means that a cylinder (s) is misfiring or is randomly misfiring. Start by checking for intake leaks; intake gaskets are a common cause of multi-cylinder misfiring. If no leak is found, the next step is to replace the spark plugs. If the problem persists, more tests need to be done to diagnose the problem, see “Possible Causes”.
