Yeah, I figured as much. I used to have an SV so I've heard of the problem before, just never encountered it. I was surprised how long it went before giving up that cylinder though, I was a good hour into that storm before anything happened. We're talking 6+inches of water on a four lane highway kind of wet. I'll have to get in there and poke around to un-clog it later, but for now I think it's ok, it was hard enough getting my hand in there to change that spark plug!There is a drain hole from the spark plug well. You probably need to clean it out.
