Low-quality fuel: Many unbranded fuel stations in Pakistan use low-quality fuel, which may have high sulfur content. This can cause the converter to clog more quickly.
Excessive carbon buildup: If the engine is running rich too much fuel, this can cause carbon buildup, which can clog the converter.
Poor engine maintenance: Issues such as misfires, poor spark plugs, and unburned fuel entering the exhaust system can damage the catalytic converter over time.
