Replace the Oxygen sensor. All your trouble codes are downstream of the oxygen sensor, and are related to it.
Once you replace the oxygen sensor (replace with a BOSCH sensor!), remove the positive battery cable, step on your brakes for 10 seconds, then reattach the cable. This will clear the codes from your ECM (Electronic Control Module).

to narrow this fault down it would be best to swap the coil,plug and injector,all too different cylinders to see what cylinder the fault goes to and then you will know the problem.
