Whenever I accelarate, I hear a faint "ssssssssss" noise coming from under the hood. I never heard anything like that before! And this only happens when I accelarate, so if I take my foot off the gas pedal, I don't hear it.

It's making me think that it's coming from the fuel system, but I don't know.

I just did a TB + WP job and got all the belts replaced. I thought that was the issue, but that didn't solve it.

Thanks.
