Coils do go bad , but in my experience at hi rpms


Not always...Had a buddie's go bad last year on a cruise...No issues right up to the point where it started backfiring like a gun blast just motoring along...Extra ECM,ballast resistor,coil, might need a chase vehicle soon with spare parts when our cars start to hit 50 years old... Been in a few cars with wiped lobes, as stated it's usually a more consistant,timed popping...
