I'd say the pre cat 02 sensor bank 1 is a likely culprit.

Hi 911monty. Thanks for your reply. I have changed the bank 1 sensor, total bugger to get out, cleared the faults but now I have misfires on bank 2 cylinders 4,5 and 6. Is this likely as I have changed bank 1 sensor with a bosch and it is not matched to the original and has thrown that one out. Not really sure how these things work.
