Hey Scotty,
I have a 1993 Mercury Villager LS. I can feel tapping on one of the spark plugs when the engine is running and it idles a bit rough. Is this a major problem or a fairly simple fix?

How much diagnosis have you done? A lot of things can cause a rough idle, especially on a 30-year-old car. Have you pulled out the spark plug to check it?

Pulled the spark plug, doesn't look fouled. In fact it looks pretty clean and dry. However, I think the gap may be bigger than it's supposed to be.
