Endless problems after power washing engine bay

[derfernerf]

Power washed my engine about a week ago (Didn't read up on it or anything, just did it). Terrible idea. It starting misfiring on the way home that night (did it at a friends house). Read up on it, someone said it ruins coil packs. So I went to autozone, had them run the CEL code, replaced the coil pack. I also removed all the plugs, wiped them off, and dabbed paper towel down inside the engine to clean up any water. Worked great for about a week. Last night it rained. I started driving to work with no problems. About 10 miles down the road, I came to a stop light, and it started missing bad. The whole car was shaking, and I started driving and I had to push the gas down at least 1/2 way to accelerate enough to not get ran off the road. Worked 6 hours, drove home, same thing. Bad misfire. I'm pretty sure its only running on 2 cylinders. CEL is flashing

Codes will be ran tomorrow, but any ideas? Plugs and wires were replaced about 2 weeks ago, and 1 coil pack about a week ago (Haven't gotten to the other yet)

Any ideas or suggestions would be great!
