I must be a DA!
So I get this new to me truck last weekend. When I get it it runs perfectly. I wash it and the next day, I decide to clean out under the hood. I know enough to not use a power washer under the hood so I use an air blower and dust it then use some watered down degreaser like I always do on cars under the hood, and rinse it off with a hand operated spray bottle. After I do this the truck starts right up but misses off idle and then finally quits missing so I think I am good to go. Well, it has rained the last couple days and nights and this morning when I am on my way to work, it is missing again off idle then clears after mid range and runs fine. It is intermittent too like something still has moisture in it. Should I remove and clean out the distributor cap and the coil wire first or does one of you who has had this problem before know what it is?

BTW jump in it at lunch to day to test it out and Bazinga! PERFECT! I hate this intermittent crap. I KNOW it has to be something wet s it acts just like My Chevy did after I powerwashed the motor. I ended up taking off the dist cap, cleaning it out and spraying a little WD in there and never another problem....

Sounds like a good idea, wd 40 will help in a lot of cases, even though ur is a 318 it would've still had a ballast resistor, but since it's a 91 it might not, if it does most likely it will be right where your wire harness goes through the firewall into the cab, it would be 2 to 3 inches long and is white ceramic has 2 or sometime 4 prongs.

Good call man, I remember finding a plug wire fault at night in my old Ramcharger and just replacing the whole set.
