Yes, a bad O2 sensor can indeed cause your vehicle to experience jerking or surging. The oxygen sensor helps manage fuel-to-air ratio by measuring the oxygen content in exhaust gases. When it fails, it can lead to improper fuel mixture, causing the engine to run too rich or too lean. This imbalance can result in jerky acceleration, rough idling, or stalling. To address this, have the sensor checked and replaced if necessary.
