Washed Engine Now Got Bad Knock?

[pgh89]

alright yesterday i washed the engine bay after that of course i got water in the coils, so i thought once the motor heats up it will be right just like every other time. plus i was in a rush to get down to willowbank anyway the whole way down which is an hour and a bit trip from my home the motor never got any better so i got to willowbank stayed for a bit turned around and went home still the motor never getting any better plus every time i went to put the foot down and pass a car it would knock really bad with the power fc reading 255 plus it was making this weird crackle sound. so the next day i got some new plugs put them in, taped up the coils in case they might have some craks in them, hooked everything back up and the motor ran smooth so i took it out for a drive put the foot down about 60% and it started knocking again all the way back up to 255 while making the weird crackle sound but the motor wasn stuttering like before the motor ran smooth before ther motor was only running on about 5 cylinders. so i am not sure where to go from here any help would be great.
