Ok so my car is running lean but the check engine light is off so i logged my o2 sensor and fuel trim ........ MY o2 sensor 1 read 0-.04 (but when cold reads like .5) and o2 sensor 2 read .84-.98 at idle
STFT1 read 17 and LTFT1 read 12 at idle but on a 2nd gear pull the STFT read 0 and LTFT read 1 and my o2sensor 1 read 0-.02 and o2sensor2 read .96-.98
I can tell my o2sensor is bad but why isnt the check engine light on and what about the fuel trim readings??
sorry im a noob any input please
