When to replace a faulty O2 sensor in a car?
If the diagnosis confirms a faulty sensor (and not a wiring issue or other engine fault that could cause a similar situation), the sensor should be replaced ASAP. In my experience, vehicles with multiple bank sensors that had a faulty bank 1 sensor, the other bank 1 sensor on the opposite bank will need replacing soon.
Why is my car sputtering after installing new O2?
Which is fine, the engine can run fine in open loop, probably wouldn’t even notice anything unless you were coming close to some performance limit or another. But when you switched to the new sensors, that confused the ECM, as it had been compensating for the bad sensor.
Why do I need wide band O2 sensor?
The operating range of wide-band O2 sensors allows for faster reaction time when correcting fuel trim and keeps the engine’s operating range as close to stoichiometry (14.7:1 air-fuel ratio), as possible. In doing so, reducing emissions on a newer vehicle by a great deal to comply with the stricter emissions laws of today.

Can a bad O2 sensor cause a car to have problems?
An oxygen sensor does not have to fail completely to give you problems. On the contrary, even a failing O2 sensor (sometimes called a “lazy” O2 sensor) may cause your car to have a few issues.
Where are the O2 sensors on a V-6 engine?
Modern vehicles with V-6 or V-8 engines could have as many as four O2 sensors — one located in each cylinder bank and one after each catalytic converter. If either the oxygen sensor in the cylinder block or the one for the catalytic converter fails, your vehicle could experience serious engine problems.
