Help Idle AFR 10 ?

[kanashibari]

Hi guys.

The vehicle on the original ECU. P2T. Idle AFR percent does not change up to 10 and the 4,500 to 5,000 rpm. What could be the problem with the very wealthy?

check your o2 and map sensor.maybe your o2 sensor couldnt the data.if your o2 sensor broken dont read the data and you always stay rich AFR.check them...

Are you running stock fuel System? Injectors and FPR?

At what revs does it start changing?
