Loud whistling sound coming from this part...
Hi All,
Well the whistling sound is progressively getting louder, seems like it's coming from this part and the CEL is on with this code P0171. Any idea what part this is and where to get it? Is this a DIY type project?
Thank You for your help!

Not sure what it is but I can tell it's a diaphragm by just looking at it.. it may have been ripped or leaking inside.
