Default getting car tuned

Anyone know if a bad o2 sensor will mess up the tuning? Or will it be koo to get it tuned with the bad o2 sensor then save up some money and get a new o2 sensor?

Bad o2 sensor will not give accurate reading to the ECU

Your tuner should be using a wideband...which should work just fine

Your bad o2 however could cause your ecu to adjust a/f ratio incorrectly and throw off the tuners work

Change it if its bad, especially if you know

That's the thing, it's throwing a code every now and then and i'm hoping its the o2 sensor cause I get bad mileage. And I can't find the harness to connect the paper clip to.
