How to fix cylinder misfire?

Inspect the spark plugs for signs of damage. Once you’ve determined which cylinder is misfiring,disconnect the plug wire going into that cylinder’s spark plug.

  • Use a multimeter to test your coil pack. Spark plugs ignite the air and fuel mixture using current transmitted from the coil pack,so a faulty one can result
  • Do a compression test if air,fuel,and spark seem to be in order.
  • Replace the head gasket if nearby cylinders don’t have compression. If the misfire is happening in two cylinders near each other,it’s probably caused by a blown head gasket.
  • Have the bottom end of the engine rebuilt if there’s a serious lack of compression.
