I'd start by checking to see if any water got into the holes where the spark plugs are.

You could try unplugging the coil packs one at a time and see if it changes the way the engine runs. If you get to one where it doesn't get worse and the miss is the same, you've found the involved cylinder. Then I'd switch that coil pack with one of the other cylinders and see if the miss follows it. If it follows it to the other cylinder you have a bad coil pack.
