Welcome to the forum.
Usually a bad COP, (Coil On Plug). The epoxy on the coil cracks from age and allows moisture in. You can do a quick test by unplugging it while it's running listening for any change. And I'm sure there's tests you can run with a multimeter, but I don't know the readings you'd look for. Google would though.
They're very easy to replace, and usually $40 - $80 a piece. Depending on where you buy them.
