My jeep hates humidity!

I inquired about a little starting problem I've had a while ago. Ive done the capacitor swap to the ecm, all new sensors, cap, rotor, plugs and wires with a high power coil. I'm almost positive that I'm getting humidity somewhere that makes my jeep crank a lot in the mornings. Once I get it started it'll start great for the rest of the day. I know I'm getting fuel because you can smell it and it pops like it wants to start. Then when I get spark it ignites and blows my exhaust apart. It acts like I have h2o in the cap but Its new and I sealed it with rtv. Its not too temperature related but definitely humidity related. Maybe I'm missing something but I'm open to ideas.

My first guess when you said humidity related was the cap. But since you say you've addressed that, my first thing to do would be use dielectric grease on all connections to seal them

Just a follow up to an old thread. Im running a screaming deamon coil with my plug gaps set at .065. Here my gaps opened up to almost .080! Here the humidity raised the density altitude which made it even harder for the spark to jump the gap. Regapped my plugs and problem solved.
