Hey, was wondering if anyone has had their 86' audi hiss when you put the key in and turn it to the on position? It sounds like a snake is in my car. I wonder if it has anything to do with the gas lines carrying fule in to the engine??? Or water??? I don't know.... Dose anyone know what this is? Thanks!
