My 1995 XJS has a fault code FF44 which the book says is a faulty oxygen sensor A bank (right)I have replaced the sensor with a 3 wire NGK unit but the code keeps reapearing after 20 miles or so.The wiring diagram shows there is a relay in the curcuit but I can not find where it is located on any relay layout.Can anybody come up with any suggestions.
