Looks like only Bank 2 affected.They won't dry easy and yes, you can do a bigger damage. Misfire can permanently damage your catalytic converters and O2 sensors.
yes
Did this problem occur after you washed the engine? Or did it just start happening when it rained? Are they "wet" as in oil soaked?
after washed engine
not oil soaked
