Hello. So when I step on the throttle I can hear this air noise along with the normal engine noise, and I seem to be burning a bit more fuel than I'm use to, which I know is a variable in most situation. I was wondering what this could be... Manifold leak? if so could it be messing with my air/fuel ratio causing more fuel consumption?

Thanks.

Could be anything, have a buddy listen for it under the hood as you rev or put load on with the brake (if auto)?

Do you have an aftermarket air intake system?
