missing and stalling when it rains

[nic2fast]

The only time I have problems with my truck is when it rains, If i'm driving down the road it will buck like the cps is going out and when I pull up to a light or stop, sometimes it will die, starts right back up. thought it was moistureso i put dieletric grease in the connector to block it out, hasn't changed anything. ???????

It's something to do with the windshield wipers. Mine does the same thing, I started flipping the windshield wipers on then right back off and it only does it at the exact second it flip them on. I've been told that the wiper motor and the computer ground at the same point and the ground needs to be cleaned but I'm yet to find that ground.

I've noticed that it seems to happen when the wipers were on, well thanks for the info, I'll see what I can do with it

Iv heard that water could be leaking down from the window into the pcm you might want to pull it out and see if there is water in there, disconnect the batterys before you pull the computer im sure a tech or someone will be along the way to help thats just my .02 cents.

turn signals , brake lights , wipers , etc. always check grounds, especially starter wires. loosen and tighten all grounds.
