You can ignore the WB unless you have one fitted.

Both banks are showing a lot of added fuel and the Intake Air Temp voltage is high.

For the fuel trims it might suggest a vacuum leak somewhere before the intake manifold or a low fuel pressure situation. Has the fuel filter ever been changed?

The IAT sensor voltage not 100% sure, the temps shows as 17 degrees, what was the ambient temp? How long had the engine been running?

Hi thanks for the reply ok don't worry about the IAT voltage that was taken when the car was not at normal operating temp. I changed the fuel filter last November. In the envious customs software under freeze data I get some codes I have included the pics. I thought it might be my o2 sensors but I am not sure. thanks

Well it could be an O2 sensor but it would be strange for both banks to be doing the exact same which is my reasoning for thinking something else might be causing it.

It can't hurt to replace them, O2 sensors are the most critical sensors for the engine as they control the air fuel mix once in closed loop mode.

There is some other stuff going on.

Something else to look at would be giving all the earths around the block and battery a good clean.

There are also some vacuum lines that run from the bottom of the throttle body to the purge solenoid that can come loose over time. A small vacuum leak will show as a lean condition.
