Honking/whining sound

[Tier]

My SC is making a honking like sound. Its really annoying and more embarrassing than anything.

The only times I hear it tho, is directly after I take my foot of the gas. Once the petal is up the honking stops.

Any ideas what it might be?

Ok I figured out what it was. It was a vacuum hose going into the SC that was being constricted making a nasty sucking sound. The SC was amplifying the sound making it seem like that's where it was coming from. All's well.
