When I'm decelerating, around 40mph and below, I can hear a hollow "burbling/gurgling" sound.
At first I was thinking maybe my tires were out of round, but then the noise would always be there.
Then I thought maybe the front control arms are loose, or bushings bad. But then that would also always be there...
Then I thought maybe wastegate rattle... but I've watched videos of that and a wg rattle is a lot louder and more raspy...
So I'm at a loss... it's too quiet to be picked up by my phone, otherwise I'd post a video. If I floor it and then let off the gas, it makes the noise, or when I'm just cruising a consistent speed and let off the gas or turn off the cruise control. It does it whether the engine is warm or cold... I can tell the frequency of it goes down as I decrease speed, until the rpms drop. Ideas?
