Were the misfires occuring on the same cylinder(s) each time? It could
also be faulty spark plug(s), spark plug wire(s) or even low grade fuel.
If the coilpack epoxy fix doesn't do the trick, you can try swapping
spark plugs between cylinders to see if the misfire(s) follow the plug.
Even if you do the epoxy fix, the internals of the coilpack maybe be
damaged, and this will not be corrected by the epoxy fix.
Another option is to swap coil packs with someone that is not having
issues............that will definitely help you narrow it down.
