    Default What could this noise in engine bay be?

    Everytime my car gives gas while idling, i hear a rattling noise from my engine bay. It sounds like as if a heat shield is loose or something. Its comming from behind my engine. The noise started to happen after i was going down my friends underground garage with the car full of passangers. I smacked the ground going down and now on idle my car keeps making this noise. Any ideas on what it could be? Thanks guys

    Is the metal bar across the rear side of the engine tray loose? Very common.
