You most likely fried some COP's. Either wait for a CEL or check each of them.

The best time to clean the motor is before you change the COPs

Remove the coils and look down in the spark plug well for water. If you find water in a well blow it out with compressed air. Driving around with a constant misfire will damage the converters. Do not use a pressure washer to clean the engine. The high pressure will force water into areas that should not get wet.
