Wet = runs bad with Check Engine

After a car wash, my 00 villager runs really rough, check engine light flashes too. After a while (things dry) all is OK again (the check engine light stops too).

I've changed cap/rotor, plugs and wires. Anybody have any ideas?

I don't know if this will help you, but here is an article I found recently when searching for a solution to problems with my van.
