I have a separate thread talking about my ordeal of a new to me vehicle not running after a detail. Well I got it running and it seems to be running fine however I notice what sounds like a light ringing - kind of like a high pitched whistle but intermittent like ringing a small bell at high frequency. Or maybe tapping a small metal cup very quickly. It's very hard to nail down because I can only hear it while driving and coincidentally there's a lot of road noise. I notice it most when... 1997 TJ SE - ringing sound?
