I like that post 650NutKase
The one about lifting the coil up off the plug with the engine running
Do you lay your nut sack on the fender or the hood latch when you do that?
Run it long enough to set a misfire code
Switch coils around to verify good or not and where the miss is
Replace the new coils with the old ones?
Maybe what were to be high quality coils are not?
Maybe you cracked a plug?
When the Chinese started making AC Delco fuel pumps, I saw a rash of bad ones right from the GM parts counter
I saw enough no good fuel pumps, that I started testing them with a battery before installing them
