[gibson]

Just wandering if anybody has had a whistling sound coming from under the hood when you give it gas. Its not all the time but very noticeable when driving.

Welcome to this forum! The IAC makes a woo sound like a train. Dogfriend has a video clip of this. Sometimes cleaning it helps, but eventually the only solution is to replace it. Check for open vacuum lines or a loose intake hose.
