hesitation when driving

I have a 1997 Safari van. Love it. It has this annoying "feature" of hesitating in moist conditions. We have done everything we can think of, from full tune-ups (replacing wiring, etc..). Spent many hours and much $. Been seen by at least 3 GM dealerships and the problem still recurs. I have tried gas line anti-freeze which I sometimes think has an effect. My regular dealership says this is a problem identified with this van with no cause or solution yet found. Any suggestions?

I think everyone has had this problem at one time or another. I was told that mine was due to a vacuum leak. I replaced a lot of vacuum hoses and did all the electrical replacements I could think of and it just went away one day. Wish I knew what exactly fixed it but I don't know.
