  • Possible rough running and loss of power
  • MIL illuminated or flashing under load
  • Possible increased emissions

Possible causes

  • Ignition fault (spark plug, coil, leads)
  • Injector fault
  • Low compression or mechanical fault
  • Intake air leak
  • Fuel supply fault

Recommended checks

  • Read misfire counters per cylinder
  • Check freeze frame conditions
  • Swap-test coil/plug between cylinders where applicable
  • Check injector operation and cylinder balance
  • Perform compression test if electrical checks pass
