My engine coil number two is crackling and sparking outside of the plug and the metal ring inside the plug is cracked and it is causing my cylinder to misfire a lot.

Hello,

I would recommend replacing the ignition coil and the spark plug as well. If you choose to do so, I would recommend replacing all of them at the same time, but it is not necessary, but highly recommended. I would also replace the spark plug wires at the same time. In the diagrams down below I have included the directions on how to test your ignition coil to determine for sure if it is bad or not. It will require you to use a multi-meter, so I have included a link below for you if you are not familiar with how to use one.

And here is a guide on replacing your spark plugs as well:

Please go through these guides and get back to us with what you are able to find out.

Thanks,
Alex
