alright here you go i see this all the time at work we have the cars detailed and when tey spray the motors off the water gets in between the plugs and the wires cause a check engine light to come the cod efor the light would be a misfire on the cylinder thats wet best thing to do is pull the plug wires off and blow air in them to remove the water then spray the inside of the wires with silicone spray so it doesnt happen again. if you have a distributor do the same to it.
