Hey Guys wondering if you could help me out with this noise coming from my engine.
When im driving and hit between 25 and 30 mph i hear this poof of air sound then a strange rattling noise,
Then it stops at 14 mph every time when i slow down?? Anyone else having this problem cuz its driving me crazy!!

Hmmmmmmm... I don't drive in automatic mode very often, but those speeds kind of sound like the speed the transmission usually shifts out of 1st and into 2nd and then 2nd into 1st.

It must be a characteristic of the car since more than one person experiences it.

My G8 and many others has a whistle noise at startup. Nobody ever figured it out so we just live with it.
