I'm sure you guys get questions like these all the time but here it goes. About a week ago my car started running rough, much like it was sucking air from a line somewhere. It has a small miss in it but I'm getting no check engine light. I took it to a shop and he found a gas line had a small hole in it. He replaced it and, with his puzzlement, returned the car to me not knowing what the problem was. Any suggestions?
