ignition coil noise

[notch351]

I am looking for help to figure out a loud fast steady clicking noise from my coil. I have swapped it out it is not a noise through the speakers. it is directly from the coil. although I can hear it from in the car. anyone ever have this issue? confused. car seems to run just fine but i am sure this is not normal and woul love to figure it out

Is it an aftermarket coil? Some can buzz.

Do you have a noise capacitor connected?

It could be spark jumping to ground. Check it out in the dark and see if you see any sparks jumping.
