Lambda high - No fault codes

[Bruce Wayne]

Interestingly, the readings i have are as follows:

Short Term Fuel Trim Bank 1 - Average 2.64

Short Term Fuel Trim Bank 2 - Average 3.56

Long term on both are the same values


O2 Sensors

Bank 1 sensor 1
Output Voltage 0.115v - Average 0.39

Short Term Fuel trim Average 2.86

Bank 2 Sensor 1
Output Voltage 0.705v - Average 0.41

Short Term Fuel Trim Average 3.33



What i'm interpreting from this is that the Bank 1 Sensor Voltage seems down and is causing a the fuel trim to lean off. But then I'm kind of fixated on O2 Sensors at the moment having just had to replace on the range rovers !!

Any alternative theories greatly appreciated.
