Pick up my rig yesterday, was running fine till this mooring.

I took it to the car wash to clean the engine compartment. Washed it and when I got ready to leave, it was sputtering and idling really hard and bad.

Got codes at AutoZone. P0306. Misfire in #6.

Changed out the Spark plug wire with new, and moved the cylinder ignition coil to another position still nothing.

Runs a tad better but when accelerating at RPMs of 12,000 to 20,000 rough acceleration. over 20,000 RPMs seem fine?

Ran codes again still same P0306

What could I have gotten wet that would have affected this?
Thanks for you help.

for those that might have been curious.
The engine dried out over night.
And running normal again.

Pro - running fine again

Con - electrical wire somewhere is a potential problem?
