Do you have cats?Sorry I swiped to type and didn't proofread before I posted
Wide band is autometer with Bosch sensor
It definitely does not go lean at idle and it smells very rich at idle
wot is 11.3 to 11.8
Cruising definitely stables more towards 14.7

Has the sensor been calibrated recently?No cats and I am unsure what the stoich is set at
Am I just creating phantom problems for myself lol
cause the car has ran good for years

They should be switching lean/rich/lean/rich…STFTs should be within +- 10%, with long terms being the same. Long terms won’t change as fast as the STFTs.I will do that today what am I looking for on my narrowbands ?
