Well I took my car in a week ago from what sounded like a belt problem. They swtiched the belt, and today I was in traffic and the sound came back. It basically sounds like a belt, maybe they just didnt do the work properly. Has anyone else had this problem. it almost sounds like my car is supercharged ( I wish) with the type of whistling it makes, its kind of a whistling and a sqeaking, I dont really care as im sure they will figure it out, but it would be nice if anyone has had this problem or a similar one, I can have them check somethign specific.
