Which are correct values returned by the 1st oxygen sensor?
Mine is floating from 10 to 760 mV at idle, and almost around 60/80 mV when at 2000 rpm.
Is that ok?
I already changed AFM 3 weeks ago. Car runs better, but I still have unstable power and sometimes a very bad idle (engine stalling). I suspect a bad correction in fuel trim maybe due to a faulty O2 sensor. Could it be possible?
