Question for you motor heads..

[Jordan]

I have a 1997 chevy 1500 ext cab p/u. Everytime it rains my truck spits and sputters. Well this morning with the 6+" of rain we had here, I hit a purty good sized puddle and my truck is almost wanting to die. I have to keep feathering the throttle to get the truck to go. I tried to "floor-it" and it doesnt respond. *** is the problem ? Thank god i was 1/4 mile from work. Also when I stop and put it in park, it idles fine for a few seconds, then cuts off....
