Ok I need your help. I went to replace both O2 sensors, passenger side came out easy but the driverside was gaulded and eventually pulled all the threads out of the manifold. I removed most of the exhaust nuts but am have difficultly getting to the one blocked by the engine mount. Do I need to remove the engine mount and jack up the engine to gain access or am I using the wrong tools? I have a new manifold ready and waiting for me when I get home, if I can just remove the last manifold nuts!
