Reviving this one I guess.
Yesterday I changed out 2 COPs on my GT. Cylinders 4 and 8 would be getting a misfire if I let the car sit for more than a day in cooler weather and elevated moisture levels (whether it be humidity or rain). Found Motorcraft COPs on Amazon for $38 each. Swapping them was much, much easier than I thought. I probably spent more time clearing miscellaneous debris from around the spark plug well than I did actually changing both COPs. Everything fired up normally after the swap...I also cleaned the battery terminals of the built up corrosion and put some of that protectant grease on them.
I'll see if the misfire stops...I just gotta wait for a cooler, rainy day to let it sit.
