I have a strange noise that might be coming from the intake manifold or the throttle body. It sounds like a moving or rotating part, noise increases with engine speed. Strange because the noise continues for a moment after the engine is shut down!

It could be a foreign object in the air box or a buzzing PCV valve.

Thank you. I will replace the PCV for sure, There is a IAC value under the throttle under the throttle body. Could that cause a noise?

Yes that is very possible. When you hear the humming or buzzing noise put your hand on that IAC valve and see if it's vibrating
