Can an old oxygen sensor be trusted for tuning?

Post by 0macman0 »

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.
