2001 Mazda MPV Question: Whooping noise out of air cleaner when decelerating.



, Cumming, GA, May 08, 2013, 18:08

Either from revving or normal driving, anything that makes the RPMs drop fast creates a series of quick but loud whooping noises out of the air cleaner. When manually revving from the throttle body i could recreate it and the whole air cleaner assembly vibrated. Changing the air cleaner and assuring all the clamps were tight did not help. I cant find any air leaks or damaged parts.

    Check for 'Grus Americana' sucked into air cleaner, see any feathers around the box?

    Check air inlet TO the air cleaner, mounting and closure hardware. Clips, screws or gromets! Good OE type filter?
