Does anyone know how to fix the humming noise after putting in a aftermarket (FRPP) Coil. I read another thread about people having the same problem. This noise almost drives me nuts. I would put the factory coil back on it but I am cleaning up my engine bay and I like the way the FRPP coil looks. Does anyone else have this problem.
