My 95 Civic LX started "missing" three days ago. It's been raining a lot.
Upon inspection, the #4 plug wire had popped up out of the valve cover -
approx. 1 inch and was wet.

After drying the wire off, and drying out the hole, it ran OK for 1/2 day
and then popped off again. I swapped #3 & #4 spark plugs, and the problem
stayed in #4. When the wire is re-inserted, the problem goes away, but
returns shortly thereafter.

Any ideas?

Thanks!
