I have a 2002 F350 that misses everytime it rains or on wet pavement. I have sprayed water and can not duplicate the problem.

is this gas or diesel? see if you have water around or over the fuse box (windshield leak) getting GEM wet, also check the wiring harness laying on the engine for damage(rubbing). if diesel check plug at cam sensor,clean and grease it.
My 99 F350 7.3 shuts down or misses when raining, all the above I have been told can make this happen, I done all this but it still happens, will post if I get it fixed.

Rain causing the vehicle to run poor is usually evidence of poor plug wires, and/or a comprimised cap and rotor, sometimes is it is also evident of a MAP sensor, but try a good tune up first.

Diesels don`t have that stuff, 02 F350`s gas don`t have wires,cap or rotors.

mine got to where it would do it even on dry days for some reason the wires from the turbo to under the battery where getting chafed cut wire back about two inches from plug solderd and shrink wrap them back together and ran great i had changed turbos and that box on side twice and of all things this fixed the problem. hope this helps lol:
