Hi All I have a 2002 galaxy 2.8 v6 with a intermittent misfire. The OBD shows its on cylinder 4, so which is cylinder 4? Its had all new spark plugs, so the next trial is the coil pack, so how does the wiring plug come off the coil? One final question (sorry to hassle) What is the actual engine in that car, I have been told its a VW engine. Would just like to know so I can try to find an Haynes manual for it. Thanks in advance Lee
