Sorry - I posted two different rants that I had. I was able to get the coil packs disconnected on my Expedition without a problem, but the Lightning has been a different story.
The other item that was frustrating me was that the rubber insert in the spark plug socket kept staying attached to the plug when I pulled the socket off. I had WD40 on it, and they still stuck together. I used blue loctite to secure the rubber to the socket. I will start again on these tonight.... hope those coil packs come off a bit easier. These really are on tight for some reason.
