You can have ONE bad coil, and when you move it you move misfires to MULTIPLE other coils. Your test does not NECESSARILY tell me you have two bad coils.
AFAIK your fire order is: 1-5-3-6-2-4 .... so 1&4 are neighbors as are 3&6
If it was one, or two, coils replacing all will certainly fix it. But I would put money on only one being bad.
