Simply put... The coilpacks can overheat when the gap is at the point of misfire.
Basically what happens is there is not enough continuous deliverance of volts from the coil. This is essential as it is required to jump the spark over the gap at the effective cylinder pressure. When this occurs the coil can in a sense overheat. The built up energy from the coil is stored for a longer period of time until it can and will lift the coilpack. The longer you wait, the more the coil can break down. You will eventually get to a point where it is basically no longer functional.
This is my understanding not to mention was cause of my coilpacks popping. Started at cyl 3 then when down the line. Checked gaps, they were much larger at almost twice desired size. Regapped them, applied antiseize, and car has run fine since.

i noticed it when i went to change the spark plugs. put new plugs in, checked again. loose again.
someone suggested the PCV value. if that's clogged. pressure may be pushing out cylinder #3...
