Extreme humidity and misfires one morning on startup.

Over the weekend we had strange weather with extreme humidity. The inside of my garage was literally dripping with water and everything was wet with condensation. I think its because the weather warmed up quickly, was humid, and the inside of the garage was still very cold.

My question is could the extreme humidity and condensation get into coil packs and spark plug tubes causing the misfire situation?

When starting the car this morning after it sat all weekend in the extreme humid conditions it through P0301 and P0302 codes. Misfires on cylinder 1 and 2.

After letting the car sit until the afternoon today when everything dried out it was fine and started / ran fine.

I have an appointment to have the official codes read and check out the issue. Should I keep it or wait and see if it does it ever again?

Car is a 2007 with 41,000 miles on it. Is it likely that at 9 years old I need to change out the coil packs, tubes, and plugs?

Probably one or more coil packs, we see this when owners wash their cars.
