You've got misfires on 2,4,6 and you have raw fuel smell and smoke, I think you have stuck/sticking injectors dumping raw fuel into the cylinders, Common problem on the 3.6L. Does the oil have a heavy gas smell? Remove the spark plugs on bank 2 and see if they're gas fouled. Disable the fuel injectors to stop injector pulse. Crank the engine and check for signs of fuel getting into the cylinders. If u do find bad injectors I would replace them all and do an oil change.
