I had a mechanic try this during my recent replacement of the belt tensioner. He said the noise persisted.
As for my guess on WHAT the part is... Googling the numbers on the side of it comes up with this
Then a further deep dive lead me to
this Russian parts site which has the mystery black box with hoses attached to it.
Further yet into the black hole we call Google, I find
this part. The above listed black box part that vibrates so intensely when the noise is going is included in this larger component.
This rather EXPENSIVE component.
I did not know that this was a 'thing' on the Vibe. This secondary air pump.
Could this be my culprit?
Anyone have any experience with this thing failing?
And where the heck are these hoses going? lol
