Run standard misfire tests--pull plug, attach to wire, ground plug threads to engine and crank to observe spark. If spark is absent or weak, try a different plug/wire to narrow down to spark problem. If spark is good, run compression test on bank to check for bad valve/gasket. If compression is good, suspect injector.
Please see my tip at http://www.fixya.com/cars/r6715318-causes_gasoline_engine_misfires .These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.
Computer sets 306 based on crank sensor phase shift when #6 fires. Minor misfire like a burned valve or weak spark may not be noticed by driver but still picked up by PCM. If O2 sensor was to cause misfire, why wouldn't driver notice that? Sorry, I'm not getting it.Computer sets 306 based on crank sensor phase shift when #6 fires.
