Engine kicks and bucks in the rain, WTF?

[daddyusmaximus]

I got a problem that only happens on a rainy day. (every day this last 2 weeks) The engine kickes and bucks violently. It's like an intermittant miss, something electronic, but it shakes the whole truck, hard. Mechanic says a new computer (It shows "internal fault") The check engine light comes on, but resets if I turn the truck off. I am confused as hell. It only does this during wet weather... you really depend on a vehicle in bad weather. If there is anyone with any ideas... If the weather is nice, she runs like a striped ape . This rain crap is getting old, and it bucks so hard I'm afraid I'm gonna break something. HELP!!!

Some people who've had this problem have found it's no as much to do with the water, as it does with the wipers being On, see if it still does it if you turn them Off.

Stumbles when it rains??

If it isnt the wipers, you could always be sucking up a bunch of water through your zoodad mod. I never had a problem with mine, but it could be. May place a screeen over it or something of that nature.
