Hey,
last month i had my car re mapped and ever since then its been running rather rich from idle and throughout the entire rev range whether on boost or not. I ws told at the time my lambda sensor was 'dead' however i just plugged my laptop into the consult port and the sensor is giving a reading...
was sat at 0.010v the went down to 0.0v after around a minute but just up to 0.180v when the throttle was blipped. The AFR was at 14-15:1 at this time (first time ive seen it above 12 since the map). The AFR then sat at 11.9-12:1 when idling once the car had warmed up and the o2 sensor output was 0.150 or 0.160v.
The car is absolutely munching through petrol and i assumed it was the sensor that was to blame but it is actually giving an output which i though was odd for a 'dead' sensor.
Also, there are no current or stored fault codes on the ecu.
Can anyone advise if this is usual behaviour for the lambda sensor or if i have another issue that need addressed?
thanks in advance.
