Engine problem on 1993 Plymouth Grand Voyager

My car started acting very strange today. It rained very hard y'day. When I started the engine, it popped back thru the air cleaner box. As I was driving, the engine would surge and the speedometer would fall back to zero then go to about 80. If I feathered the throttle, it would run pretty good. I haven't had anything like this before. Any ideas?

Sounds like water got into some of your engine electronics. Let you car idle and run the heater for hours until it really dries out and then see if everything is normal.
