Metallic vibration in engine bay around 1750RPM

[110321]

3300 miles CX5 Sport. Was wondering if anyone else has experienced this and/or what it might be? It's subtle, but it definitely sounds like something is loose. I ruled out interior noises / loose things in the dash.

Cheers,
Brian

Typically on modern cars (and Mazdas certainly have their share of this) this type of noise is caused by a loose heat shield. I haven't been under the hood on mine much since I just got it a week ago, but I did notice a rather large shield attached to middle of the firewall behind the engine.
