Is the stock BOV supposed to release air while the car is sitting at idle?

 

what do u mean? at idle u should be pulling negative vacuum into the engine. the BOV should close itself.

 

Well when I am sitting at idle I can feel air coming out of the bov hose if I have it taken off of the intake. I dont usually run it like that, I just wanted to feel out of curiousity and now Im wondering if air is supposed to come out when the car is just sitting idling.

 

Yes, at idle, the stock ABV is venting some air. As you begin to transition from vacuum into boost, it will close and allow the car to build boost.
