hesitation when driving

3206 Views 8 Replies 8 Participants Last post by  gtkane
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?
