I had some misfire issues on my corolla 99. When I took out the boot to spark plug #2, i notice water condensation (literally droplets) around the boot and where the spark plug meets the engine. I'm not sure where this condensation comes from. I unscrewed the plug and it's oily black.
I tested all four wires with a meter and found that wire #2 had no continuity. I wiggled it but no use.
According to this site below, it said that
"Moisture – If moisture becomes trapped in the spark plug hole or between the plug and the wire, it can cause arcing. This will cause permanent damage to the spark plug wires and possibly the spark plug as well. "

So, do you think it's this moisture that killed my wire? Where did this moisture come from? It seems like somehow it seeped through the spark plug..but how? I don't know how long this has been going on, but wire #2 is completely dead and it's only recently that CEL reports of misfire.
Thanks,
Gordon
