Let's go with the obvious and assume that moisture is invading a marginal electrical connection. You're past the disintegrating wire harness years so the main places to check would be the ECT sensor connector (under the intake manifold) and the harness block connection at the firewall. Open these connections, use spray contact cleaner, apply dielectric grease to the female pins and re-connect. For the block connection, make sure the pins are firmly pushed together from the back sides. For a short term fix you can also use WD-40 to drive the moisture out of electrical connections ("WD":: Water Displacement).
