Then again just looked at the readings, what does the lambada measurement tell us? Thats a fail too, If the sensor is knackered then the ECU all over the place. Someone who knows abit more than my stab in the dark will be along shortly

Tose are my first 2 thoughts - I'd definitely be looking for air leaks first, followed by testing the lambda sensor.
