Noise when starting and turning off car on 2004 Nissan Altima

When I start my car, turn off my car, and press the accelerator I hear a noise that sounds like a digital camara taking a picture that sounds like its coming from under the hood. Is this a normal noise for these cars?

That is normal I forget what it is but it is normal, it may be the flap in the intake manifold or the automatic throttle control in the throttle housing.
So it is normal for it to be loud enough that when I drive people they can hear it and also everytime I touch the gas pedal it makes the same sound? I would just like to know because its still under warrenty and I will make the dealer fix it if its not right.
not a normal noise the electric motor mount is bad huge repair cost, you can easily disconnect bc you really dont need the electric motor mount.
