Hello,
I have a 02 Dakota with a 6 cylinder. It sits out in my driveway and after it rains my Cylinder mis-fires. This is with out driving it and just sitting over night.
Any Thoughts?

what is happening is the vent on the dist cap is letting moisture into the cap. the fix: take the cap off. fill the vent with j-b weld. use wd-40 or starting fulid to drive the moisture out. also check that the windshield washer hose has a hole in it. been there done that bought the tee shirt

bad wires, cracked coil and a bad seal in the distributor allowing moisture into it, do a tune up, spark plugs, cap, wires, and rotor, check the coil pack for a cracked casing
