misfiring is from plugs , HT leads ,moisture in the circuits and injector problems including low fuel pressure. use HT lead bridges to stop leads touching each other, clean out the interior of the distributor cap. ensure that the HT leads are pushed fully home in the cap and on the plugs . clean the distributor outside so the that spark cannot track through the dirt/oil.
Depending on the year, it's likely bad wires or a bad distributor cap. You can recreate the problem when it's dry by filling a squirt bottle with salt water and spraying the wires with it while the truck is running. You'll either get a nice light show or it will start to stumble/stall.
I think you should head to a mechanic. Sounds like you got water in the fuel system. You could possibly resolve the issue by filling up with a fresh tank of gas, but that could also cause more problems if there is a lot of water in there already. I'd take it to a trusted mechanic.
this is called, Engine stall. it has many causes. 1: lost DC power to the EFI system (corroded fuses?) 2: bad engine compression for many reasons but not doing the 60k service is #1 , for ever. 3: bad spark (and timing) 4: bad fueling, too much or too little. we use simple cheap tools to find this problem after doing the 60k mile service.
its old car, most i see are trash, 10 or more show stoppers. bad. all ignored by owners. #1 is the 60k skipped. i just restored a 91. and it had 20 stoppers.
If a spark has no path to discharge, it will often find a weak one or create one. If your wires or plugs are so bad that they cannot pass a spark, the coil will discharge elsewhere. It is a great coil. I have seen brand new plugs completely disable an engine. Completely. I have seen wires completely fail on their maiden voyage. The plugs were Champion BRF52 on a Ford, the wires were Belden for a V6 Mercury. I do not recommend Champion plugs, at all. I do however like Belden quality. You would not suspect them, but... Suspect them. Pull one out lay it on a steel part of the engine, and see if it sparks. If not, replace them. For wire, try to start the engine at night, watch in the dark for arcing wires. Replace them.
Check to make sure your fuse is set all the way down first. Could be a bad ground too. Check the wiring at the wiper motor and maybe clean the ground and terminals with either alcohol or electric cleaner and make sure the are dry before you plug it back in. It sounds like a power to the wiper motor issue. If that doesn't fix it your wiper motor may have an internal short.
When you replace spark plugs, it is highly recommended to replace the plug wires as well, if you have bad spark plug wires you will not get any fire from them, also have your coil pack(s) and ignition module tested.
