  7. Remove the spark plugs. You will need a socket extension and a 5/8 socket to remove the plugs.  Be gentle.  They are prone to breaking off in the cylinder head.
  8. Once you have the plugs out, inspect them to make sure they are not fouled, covered in oil, or have straps missing.  If they do, you have bigger problems than just spark plugs.
  9. Install the new plugs, put the ignition coils back on, and reconnect them.
  10. Start the car and make sure the engine is running smoothly and not shaking.

If the check engine light was on, it will take a few days for it to reset it on its own. Or use an OBD-II scanner to reset the check engine light yourself. Follow this guide to learn how to reset the Mitsubishi check engine light.
