          here are some additional symptoms of a bad oxygen sensor:

1. Poor fuel economy: A malfunctioning oxygen sensor can cause the engine to run too rich or too lean, which can result in decreased fuel efficiency.

2. Rough idling: A faulty oxygen sensor can cause the engine to idle roughly or inconsistently.

3. Engine hesitation or surging: A bad oxygen sensor can cause the engine to hesitate or surge during acceleration or when maintaining a consistent speed.

4. Check engine light: A malfunctioning oxygen sensor can trigger the check engine light to illuminate on the dashboard.

5. Failed emissions test: A bad oxygen sensor can cause the vehicle to fail an emissions test due to increased levels of pollutants in the exhaust.

6. Rough running: A faulty oxygen sensor can cause the engine to run rough, with noticeable vibrations or shaking.

7. Poor performance: A malfunctioning oxygen sensor can lead to reduced engine performance and responsiveness.
