Several signs indicate a failing catalytic converter in a Toyota Camry:

Reduced Engine Performance: A clogged o r failing catalytic converter can restrict exhaust flow, causing poor engine performance, sluggish acceleration, o r stalling.
Poor Fuel Economy: A blocked catalytic converter increases engine workload, leading to higher fuel consumption.
Sulfuric Rotten Egg Smell: A damaged converter may allow unburned fuel to pass through, causing a sulfuric odor from the exhaust.
Rattling Noises: Loose internal components o r a clogged converter may cause a rattling sound, particularly when the car is idling o r accelerating.

If you notice any of these symptoms, it’s important to have the catalytic converter checked immediately.
