The vacuum canister behind the airbox, Is it normal to have a humming/buzzing sound when at idle. Just want to know before I fork out $150 for a solenoid that I may or may not need. If someone could take a listen to there's and let me know that would be much appreciated. thanks.

If you are unsure, just unplug the electrical connector on the solenoid to see if the buzzing stops.
