Daughter has 04 jetta 1.8t. Idles very rough but drives wonderful. In the back of the engine there is a rubber part about the size of a shot glass that has hoses coming to and from it that is leaking air. When I put my finger on the leak the engine idles even worse. What do I need to do to fix the idle problem?
