I noticed it last night after i had parked at Best Buy. Opened my door with the engine running and I heard a hissing sound, almost like an intake, but it was pretty loud even with the hood closed. I opened the hood and it seems to be coming from under the intake, or in that general area. I am thinking an intake gasket leak, but i'm not sure b/c it doesn't get louder when i rev the motor or anything. Any suggestions?
