I installed an AFR gauge today but I am getting lean readouts.

The gauge reads the leanest reading all the time and rarely goes into the optimal range. Only the first few lights light up showing lean.

The AFR is installed properly and I have swapped the unit out to rule out a bad gauge.

Is my lambda pooped? I dount the car is running that lean as it should be overfueling currently as it is on the std map.

if the afr gauge uses the oem o2 sensor then i would not even take any notice of what it says as they are crap! when on full throttle its not used anyway.

Agree, the AFR is now ready to be filed in the bin.

Ill get me a wideband one instead.

however it would appear your o2 sensor has died so replace it anyway.
