I have an '85 GL Vanagon.   Its been missing lately so took it in to my local VW dealer last week.  He couldn't find anything wrong.  This morning, after a good rain during the night, got in and took off.  After about a block, the Vanagon started missing so bad that I  couldn't hardly accelerate.  I had to 'feather' the engine just to make it back to the house!  I've got a feeling that my problem has something to do with either the moisture in the air or water coming up into the engine from underneath.  My plug wires are only about a year old.

Anybody got any ideas?
