Remove the plug and look at them.
Check the gap.

While engine is running remove the spark plug wire (lead) from the plug.
* If the engine slows down, that cylinder is firing nicely
* If there is no difference that cylinder was not working

But you can get shocked doing it...use insulated pliers or leather gloves.
