So its been a few mornings now where I let my car warm up before heading out to work, and when I get to my car there's this whistling sound, i'm guesing some type of vacuum line.
As I drive off the sound is gone.

Anyone ever experience this situation?

 

If it is a squealing noise I would say it could be a belt, but it sure sounds like a vaccuum hose to me....just check em all out, it sounds like an easy fix.

 

It's def a air/vacuum line of sort.. .wish I had more free time on my hands to find the culprit. Thx for your reply though.
