I am having a problem with water building up in the spark plug hole for cylinder #6 (second from the front drivers side) causing misfires. The first time this happened was about 2 months ago, blew it out with air and everything seemed fine, it did not come back right away. It happend again last week while I was on vacation about a thousand miles away from home, this time I had to buy a new coil, after another thousand miles of driving home there no sign of water. Pressure testing after the first incdent a couple of months ago found no leak. Does anyone have any ideas on this one?

p.s. the night before the problem when I was on vacation I was in the mountains and the temperture was colder than I am used to this time of year, probably in the mid 20's
