Car misses like crazy only when it rains
 

What could be the cause of this? I searched the code before and searched it on here and said internal in the computer. Any help would be greatly appreciated, will try and get a code on it tonight

I would say your spark plug wires are probably bad.

Thats my vote. Seen it countless times from cracked O2 plug or cheap O2 extensions not sealing up.

Cracked coil pack

You can test these theories by doing things like
misting plug wires and coil packs one at a time
with water. Try it in the dark and you may see the
spark clearly.
