This depends on how it failed.

  • If it is plugged, stuck closed or otherwise prevented from allowing flow it may cause ping at mid to high throttle settings and will fail smog inspection.
  • If it is stuck open or leaking past pulling a spark plug wire will increase rpm. It will not idle correctly, will miss hesitate and just mess around generally.
