Default Rough Idle, When raining?

I don't think my C4 likes being in the rain... and I don't blame her...

Any ideas where to look to see why she idles rough, when she's in the rain?

I agree also. I'm thinking maybe there is moisture getting into the cap and causing it.

Thanks gents, I'll begin there!

Just had a TPS replaced... maybe something was left loose when they were looking around under there.
