LTFT and STFT were pegging and AFR still showed lean. |
Yeah, my stft high only during idle and is also when the code usually pops on. Typically what I noticed is when I resealed my v bands pre o2 sensor and reset the code, I did a lot of immediate driving which meant very little time idling. The day I left the car on outside my shop is when the cel popped back on.
