Has anyone encountered excessive noise on the AM band in the stock AM/FM/cassette stereo? When the ignition is on, there is noise somewhat like what one used to get when using the old style spark plug wires (this is not the problem here - brand new stock GM wires have been installed). I had the car back when in warranty and was told that this was "normal noise". I was thinking of an intermittent antenna ground but the noise stops completely if the key is in the "accessory" position. Any experience with that?
