Wierd Engine shutoff sound!

[Haziness8]

Wierd Engine/Vacuum? buzz humming sound. i get this wierd sound everytime i shut off my engine. comes from the back left hand side of the upper intake area. not sure what it is or if its bad. in the video it will sound like a buzzing sound changing pitch for a second or 2. check it out

ok the link dose not work but my guess is it is the egr vacuum valve disconnect the vacuum line that goes to the egr valve and it should stop or atleast change tone then put your finger over the end of the line and it will start again if that happens then it is that vacuum valve replace it or leave it and it will be ok till the check engine line comes on then it will have to be replaced

the egr valve vacuum line is the arrow on the right and the vacuum valve is right behind it

but the sound is coming from the left rear of the intake manifold area. could it still be the egr problem?

Try disconnecting some vacuum lines. not sure without seeing/hearing it for myself. I think their is a vacuum line going to the heater control valve on the heater core lines try that also their is an inline check valve that might be a possibility also.

do you have the air suspension? it remains active for like 40 mins after you shut off and makes a buzzing noise while its pumping air.

Ah! did not think about that but he says left rear and that would be in the left front.

Also sikamikanico816 do you mean left as if you are sitting in the drivers seat or facing from front of car?
