Hi all, 

 

I've had some trouble at the last few MOT's with high emissions on the fast idle test. I've just done a reading on the ECU and I think the data is telling me my Lambda sensor is duff. 

 

Can anyone confirm my suspicions on the exported data below? From what i have read elsewhere i shouldn't be getting a lambda reading over 1000mV but mine is fluctuating quite a lot and regularly over 1000mV.

 

Thanks,

Pete

Can you post the emissions test data? An ignition fault will cause unusual lambda readings which then also cause the ECU to try and compensate making it even worse. The emissions data can determine the cause.
