Im betting you got some water down where the plugs are. Id say take em out and get a shop vac in there to get water out and replace with new plugs.

Disconnect the negative teminal on the battery. get in the car turn on lights, hit brakes, try start the car. let sit another minute (this is to release any stored memory). then reinstall the negative terminal start the car.
It might run rough for a few minutes but that is the ecu making its adjustments...
This is also how to remove any check engine light. but if when you start again and check engine light comes back on there is a certain problem.
