Motor loss power and skipping

As you found out, you never hose down your engine without protecting the wiring and electronics. Let the engine bay dry out, remove as much water as you can. I suspect something else is wet right now, check all wire connectors and fuses

Wait until after dark and run the engine. Look for any sparking or arcing under the hood! You'll be able to see it better in the dark. If you have a distributor cap, remove it and dry it out. Dry out the distributor too. Hope that helps! Jim
