Dealer said it was OK. But there was still a gurgling noise that really bothered me. I thought they were just being lazy. Well, an after thought tip from dad solved the problem. It was the gas. The cheap, although expensive, gas was making a sound simliar to knocking. some additive and putting in some mid grade did the trick. she sounds and drive great now. anyone know how to avoid the power loss from using the air conditioner?
