What are the symptoms of a bad catalytic converter?

If your catalytic converter is malfunctioning, you may notice several telltale symptoms. One of the most common signs is a significant reduction in engine performance, often experienced as sluggish acceleration. This occurs because a clogged or failing catalytic converter can restrict exhaust flow, causing engine power to drop. Furthermore, you might detect a distinct sulfur-like or rotten egg smell, which indicates that the converter is not effectively breaking down harmful substances. Consequently, your vehicle’s fuel economy may suffer, resulting in increased trips to the gas station. Moreover, the check engine light might illuminate on your dashboard, signaling the onboard diagnostics system has detected an issue with the emissions control system. In some cases, drivers may also hear a rattling noise coming from underneath the vehicle, particularly during startup or driving at low speeds, which could signify internal damage to the converter. Monitoring these symptoms closely can help prevent further damage to your vehicle and ensure timely replacement of the catalytic converter.
