Last year I has a misfire on one of the cylinders. After pulling the offending coil pack off, testing the voltage and resistance across parts in that area and checking the spark plug everything looked good. I replaced the spark plug, as I couldn’t find an issue, screwed everything back together and all was fine. That was it for the year and the issue didn’t reoccur.
The other day, when I pulled the car out for it’s MOT, there was another misfire on a different cylinder. This time I thought that I’d just pull the coil pack and pop it back in. Bingo, it cured the misfire.
Today I pulled the car out and the misfire was back but on another cylinder! ? Again I just popped the offending coil off and put it on again and the problem was gone.
This is a bit of an odd one.

Any ideas what’s going on here?
