So this is something that has been persistent since I bought the car over half a year ago, and I'm wondering if it matters. Obviously hasn't affected function: and I spent the summer fixing those things that were much more necessary.
But now I'd like to worry about it
Almost at random, I haven't yet made a connection between driving habits and when it manifests, I'll hear a quite audible hissing vacuum leak that seems to come from the rear of the car. But the acoustics could well be deceptive: just because it sounds like it's from the rear of the car, doesn't mean it's not simply reflecting off of the rear of the car and fooling the ears.
It's only when I'm backing out of the driveway and at low speeds, but that could simply be that highway noise drives it out.
What should I start to look at?
