Reduced acceleration: A clogged catalytic converter restricts exhaust flow, causing a noticeable decrease in power and acceleration.
Poor fuel efficiency: The engine has to work harder to expel exhaust gases, which leads to increased fuel consumption.
Excessive heat buildup in the exhaust system: A failing converter can overheat, causing the exhaust system to become extremely hot, potentially damaging other components.
Strange odors: You may notice a strong, sulfur-like smell from the exhaust, which is a sign the converter is failing.
Rough idling: The engine may idle poorly due to exhaust backpressure.
