It kinda sounds like you may have a weak wire anyway.

If you are arching across the boot somehow, the wire should be replaced anyway.

Have you checked the cap and rotor? If your wires got that soaked and had condensation, then its totally possible they got the same treatment. BTW, next time wait until the engine is cool before doing that....

It sounds like you only a dry vac and a hammer.

Dry vac to suck up the water, a hammer to beat on it if it keeps running rough.
