    After it kicks into low idle, the vibration of your car changes and you are probably hearing the heat shield on the catalytic converter shaking. Probably broke a weld with age but, this is not a serious prob. just annoying. You can get it rewelded on at a shop.

    Without the benifit of hearing the noise it would be guessing. Could be a timing chain tensioner losing oil pressure. Common problem.
