There be a sensor per bank, and maybe even pre cat and after cat Lambda sensors.
Get a multimeter on the signal wires and check them.
It is likely it is the fault, bt need to check the signals from each...once warm always good, at idle.
Ensure good switching between 0.1 and 1v.
thanks for that mate will try that and see what happens do you know a good website for cheap ford parts as the main dealers are as you would guess very expensive
