So you know how the car revs higher at cold start with the blue light on, well being that my car is garage kept and I live in Florida, so I don't let the car heat up very long.

so once I pull out of my driveway and drive to the stop sign maybe 20mph max, I hear a whistle like the car is sucking in a lot of air, it just started maybe 2 days ago. but once I stop and drive again it doesn't do it.

I was just wondering is anyone else has had this?

its a new 2013 mzada3 with Skyactiv, automatic, 1,400 miles.

Any input is helpful, thanks
