Default lots of rain and poor running

well last night I took my car out and it was running great. I parked it out in the rain and the wife and I went into a restaurant to eat. I come out about 2 hours later and the car is running like crap. Wide band is reading 10-13:1 and 13.5 at idle, just way off. I can't tell if it is a wet spark plug or wire of if perhaps the plug for the second 0xy sensor is getting wet perhaps. I just did a 6mt swap (car has run perfectly since) and the lower plug at the rear of the tranny where the second oxygen sensor plugs in was a tad bit exposed. Also, when I had the car tuned back in december I had to replace the oxygen sensor on the header, it was bad. Is it possible that the second sensor just went bad???? How much effect does the second sensor have? I thought with the accessport that it didn't have that much effect? I remember my 2.5RA with jdm 2.0 swap would run bad in heavy rain too?
Any help is greatly appreciated.

Oh, no CEL either....
