How to change plugs and wires on 1997 Mercedes-Benz C280
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.

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?
