Bad spark plug?

What kind of noise if any will emit from a bad spark plug or wire?

If it's loose or a plug wire is arcing it can make a tapping sound.

I did a plug change and got a bad one out of the box. PCM threw a code for a misfire in my #5 cylinder. Changed the plug and everything was good as new. Never made any noise, though.
