Can an old oxygen sensor be trusted for tuning?
Can an old oxygen sensor be trusted for tuning?
Just wondering if there is some mileage cutoff around which the original 02 sensor becomes inaccurate? I have 115K miles, and noticed I'm running pig rich for some reason. Should I trust it and remove fuel?

It depends on how the o2 sensor has been treated. I would recommend that you try replacing the sensor to be sure.
