Car stumbles when it's wet/raining outside. Whenever I start traveling in the rain the car will occassionally stumble at low throttle position but if I increase the throttle opening it'll eventually kick in and snap you back in the seat. Any ideas as to where the water is getting to and causing this?

Do you have FTRA? Possibly sucking up water into the motor? I would also check all of the weatherstipping around the hood. I suppose its possible for water to leak in and find it's way to electrical connectors/sensors.
I had a bad water leak in my 70 Chevelle and couldn't beleive how fast it moved once it found its way into my car. Moral is, don't hesitate to check very unlikely places, because they may just be an entrance point. Good luck, I'm sure it's frustrating.

Nope, no FTRA. It'll go away with increased throttle position. Again, only does it when it's raining outside. It'll disappear after a few minutes of driving.
I think there's an exposed wire somewhere. Any ideas as to which wires would cause this?

Yep, pull the O2 connectors apart and check for water in there, it will cause a stumbling idle and misfires.
