skipping in the rain?

[jeff3869]

hello all, I recently bought a 2001 f350,with the 7.3 psd. It runs great when its nice outside. BUT when it is raining it will shut down at red lights and skip from time to time go down the road 50 , 55 miles an hour. I have no clue . Does anyone have an idea. Thanks to ALL .jeff3869

I remember reading somewhere that someone had CPS problems when it rained. It might be worth your effort to pick up a different CPS and see if that helps.
