What are the symptoms of a bad catalytic converter?

Symptoms of a bad catalytic converter: decreased engine power performance, engine weakness, abnormal engine noise, increased fuel consumption, and difficulty in ignition. Detectable symptoms during inspection include: increased exhaust pipe resistance, worsened emissions, engine overheating, incomplete combustion, and disrupted engine air-fuel mixture concentration. The catalytic converter is an important device in vehicles used to control harmful gas emissions, primarily employed in gasoline engines. The catalytic converter is typically installed in the vehicle's exhaust pipe to utilize heat from the combustion chamber to activate the catalyst, accelerating the reaction of the catalytic converter, which can control the emission of two to three types of harmful gases.
Recently, my car has been experiencing some issues. I've noticed a significant decrease in acceleration - the engine roars when I press the gas pedal but the car barely moves, and fuel consumption has increased by about 15%. The most noticeable symptoms are a pungent rotten egg smell from the exhaust and popping noises from the tailpipe during idle in traffic. Last time I refueled, the attendant pointed out that the exhaust smoke was unusually dark. A subsequent diagnostic test confirmed the oxygen sensor was throwing error codes. I'd advise everyone not to ignore power loss symptoms - these repairs can get expensive, so it's better to address them early.
