I think you are right. Wet conditions and poor performance tend to indicate an electrical problem. I know, I sound like a broken record, but....... what about the rotor. You tested multiple caps but you are using the same rotor. There have been a lot of posts with 1996 to 1999 that end up a faulty rotor or cap. I was one of them. I never could figure out what was wrong with the cap or rotor. I tested the continuity on the cap and it was good, no arc lines and light corrosion. Maybe some one else will chime in, but it seems in the last couple of years there are less people on the board.
