Mike,

I'd be willing to bet a sum I can afford to lose that it's the ECU
connection taking in moisture. Any ideas about coating this with something,
either a lacquer or spray-on dielectric grease or something like that? There
must be a product people use. The problem with a hard substance like lacquer
would be that the first time you open the connection you break it, then have
to recoat ad infinitum or at least ad finitum vanagonae. Maybe there's an
electrical protectant that remains pliable?
