Check your bank 2 plugs for colour (do they look hot like they running hot ). Check you EGR Exhaust Gas Recirculation valve (looks like a 80mm diameter spaceship with a vacuum line to the top of it) If this remains closed the engine runs very hot and causes misfire. Possible causes are EGR not opening are 1) perforated diaphragm 2) encrusted valve stem 3) clogged exhaust gas feed pipe. A quick check for function: run the engine and remove the vacuum tube. The engine note should change as the tube is connected and then disconnected. Also pushing on the underside of the EGR with your fingers to lift the diaphragm to open the valve should also result in change in engine note. If its not working just disassemble the EGR and clean with carb cleaning spray, also clean the exhaust gas feed pipe likewise.

go there look up the codes there all there

ok first off if there is no connectivity you will need to confirm this by testing the leads to the O2 sensor itself, try to back probe them with a T pin so that you don't disturb the plug too much so that you can rule out a fuilty plug connection, make sure you have voltage, I would assume this is a 4 wire O2 sensor which means that its a heated sensor meaning it has a heater in it to jump start the collection of data @ the sensor.if you have voltage check the plug it self it there is voltage on the O2 sensor side on the plug then you have a bad O2 sensor
