Look for a layer of dust on the outside of the plugs, or on the inside
of the coil where it plugs down over the spark plugs.

A thin layer of dust is OK when it's dry.  But add moisture from humidity
in the air and it can become an easier path for the high voltage to take
than firing the spark plug.
