Hi
Does anyone know what the normal readings onthe commander are for the O2 sensor, mine stays static at about 0.08 at idle and then jumps up to about 0.9 when you blip the throttle.

Just trying to rules this out as the car is running mega rich and not accelerating, tried swaping the maf but no joy so time to try the Lambda sensor.

Thanks
Jon

 

could be faulty or running too rich for it correct the fuelling enough on the lambda..

try turning lambda off and see if lambda reading changes..
ETC-->function select--> o2 feedback - up arrow turns on down arrow turns it off

 

Hi
Thanks for replying and sorry its taken so long for me to check (long story involces football, pain, hospital, crutches)

I've turned the lambda off as per instructions and its about the same 0.12 under idle then under load moves up to 0.98 and stays around that until I lift off.

Not sure if this means its broken or something else is, any advice appreciated.

Thanks
Jon
