Yes, a clogged catalytic converter can significantly affect the performance of your Suzuki Alto. The catalytic converter works by converting harmful gases in the exhaust into less harmful substances. However, if it becomes clogged o r inefficient, it can restrict the exhaust flow, leading to poor engine performance.

Signs of a Clogged Catalytic Converter:

Sluggish Acceleration: The engine may feel slow to respond when you press the accelerator, and you may experience difficulty reaching higher speeds.
Rough Idling o r Stalling: The engine may idle roughly o r even stall because the exhaust gases are not flowing freely through the system.
Reduced Power: The vehicle may feel underpowered, especially when driving on highways o r under load like going uphill.
Solution:

Examine the Exhaust System: If you suspect a clogged catalytic converter, it’s best to get it checked by a mechanic. They can perform a backpressure test o r check for excessive heat in the exhaust system.
Replace o r Clean the Converter: In most cases, a clogged converter needs to be replaced, but sometimes it can be cleaned if the clog is not too severe. However, cleaning doesn’t always restore it to full functionality.
