My 2010 jeep jk misses while idling and runs ruff when its raining or just damp outside, Any ideas as to what it could be would be greatly appreciated.

On a nice day open the hood and take a spray bottle with some water in it and spray around the engine. Spray the water at the electrical connectors and around the ignition coils. See if there is any change in the way the engine runs. Did the check engine light come on?

Sounds like the distributer is getting wet. Check to see if the cap is one correctly.
Except they don't have a distributor...

I forgot to tell you to have the engine running when you do this.

Just a WAG here, but do you have an aftermarket intake, commonly referred to as a CAI?
