Cars that have a faulty oxygen sensor will commonly have a poor idle, jerk erratically at a steady throttle or emit a rotten egg odor from the exhaust pipe. If a car has a bad or broken oxygen sensor, this will cause the car to operate less efficiently, causing other problems like the car being difficult to start, its "check engine" warning light coming on or an abnormally high rate of fuel consumption.
