I have a possible problem, only does it for a few seconds, not very loud. For those who can date themselves by this description: It sounds like a very low volume metallic rattle/flutter like a bad heat riser valve (part of exhaust system) makes on early model General Motors (gas) products (70's ish)........ Let off the throttle at low speed or a high rate of deceleration with brakes and you hear this from the engine compartment area. Seems more noticeable from the passenger seat. Higher volume at first appearance, reduces in intensity over a few seconds, then quits 50 feet or so before you come to a complete stop. No indications of malfunction, driveability, or MIL indications. Showed up a couple of months ago....
