I have 98 GMC Savana van 5.7 V8 when it rains even if van is parked then I
drive it runs really bad. It has almost no acceleration and seems like it
would stall. The engine light goes on and sometime misfires. When it stops
raining about the next day it runs fine.

Go to a dark shop, open the hood & taking a spray bottle "mist" around
the plug wires with water. If the wire's are going bad you'll see
some neat effects. (good cheap starting point).
Otherwise we'll need a bit more info, Last tune up, integrity of
wiring harness, mileage and type of use of Van, etc, etc
