Think I can help you out. More than likely your problem is comeing from the rubber boots that connect to your coil packs. Since they are down in the cylinder head they get alot of stress from heat and start to harden and crack allowing spark to arc inside the cylinder head. This causes two problems one you get that cylinder misfire code on your code reader, two the arcing in the cylinder shorts out the coil pack.

So, I recommend changeing those spark plug boots on your remaining coil packs and that should fix your problem.

Hope this helps you out.
