Hi there had restricted performance on my xj sport brought like this. Had both knock sensors low input, heater oxygen sensor, coolant temp codes up on my mates snap on reader. Also had a missfire which is now sorted (injector) but still getting these codes up with the restricted performance. Any one have any ideas what could be up?
