A flashing service engine soon light is warning you that the engine is misfiring and the catalytic converter is being damaged. Have the computer scanned at your local Advance or Autozone. They'll do it for free. A trouble code P0300 is random/ multi cylinder misfiring, P0301 is cylinder #1 is misfiring, P0302, is cylinder #2 is misfiring, etc. Are you due for a tune-up? If so, try that first. HTH. -Jim
