Thanks, ***** ***** does not speed up I am having a hard timing blaming something spinning inside the engine. My suggestion on things to listen closer to are the serpentine belt tension the timing tensioner area and the catalytic converters. A tensioner arm or spring could be to blame as well as a baffle in the converters.
