Default sputtering in rain

my buddys 98 trans am is having a sputtering issue but only when it rains. But this last rain storm has caused the car to sputter more than before. It does not do it all the time but when it does its bad. Seem like a wet sensor somewhere maf, crankshaft sensor...Any opinions? thank you

Possibly 02 sensors....if he has some sort of extensions on them for headers.

Check the plug wires, and also, does he have a CAI? Might be sucking some rain into the maf.
