Catalytic converters clog primarily due to the accumulation of carbon deposits, unburned fuel, and contaminants over time. This can occur from engine issues, such as misfiring, which causes incomplete combustion, or from using low-quality fuel. Additionally, excessive oil consumption or a malfunctioning oxygen sensor can lead to increased buildup. When clogged, catalytic converters can restrict exhaust flow, resulting in reduced engine performance and increased emissions.
