I have the same thing happen to my car usually during colder weather or when I drive short distances for an extended period of time. For me it happens below 3000 rpm when I let go of the gas then I go back on really fast, It sounds almost like a rattle coming from the engine. My best bet is that it could be the valves but it doesn't sound like anything to worry about.
