Can you test the oxygen sensor on a car?
Oxygen sensors can be tested both on the vehicle and off, but many prefer to leave the oxygen sensor on the vehicle.

Can a vacuum leak cause an O2 sensor to stall?
Creating a vacuum leak should cause the voltage of the 02 Sensor to drop below .1 volts and then rise above .5 volts when the leak is subsequently plugged. If your vehicle does not have a vacuum port or if creating a vacuum leak causes the vehicle to stall, you can preform a propane enrichment test.
