Whistling noise when you take your foot off the accelerator

My apologies...but my searches came up blank on this one:

I get a whistling noise when i take my foot off the accelerator on declines (like a vacuum). Noise goes away at a complete stop or when gas is applied again. Makes the sound even with the AC/Heat/fan off. Seems like it's from the engine compartment. 2014 Overland V8. Any thoughts? Thanks!

Re: Whistling noise when you take your foot off the accelerator

My wife's 2012 Jeep Compass had this slightly. Happened after I changed the engine air filter the first time. Could never pinpoint it or make it go away. Prior to that, the only time I ever encountered it was with not-fully-enclosed C.A.I. kits, like the K&N.

I would check the engine air filter assembly, make sure its all tight and sealed.
