The Honda Accord has a known issue with engine oil leaking from the ignition distributor shaft seal.

Leakage from the shaft seal coats the electrical components of the distributor with engine oil causing:

  • Failure to start 
  • Engine randomly misfires 
  • OBD Trouble code(s) P0300, P0301, P0302, P0303, P0304, P1336, P1337 
  • Engine vibrations  
  • Hesitation or stalling 
  • Cleaning the distributor cap and rotor can help or resolve driveability issues temporarily, but the mentioned issues will return shortly.

    Once this issue is diagnosed, the ignition distributor shaft seal must be replaced, and the distributor shaft bearing must be inspected.
