Power loss: Yes, a clogged catalytic converter causes exhaust gases to back up, creating pressure in the engine. This backpressure can reduce engine performance, leading to a noticeable loss of power, especially when accelerating.
Stalling: If the restriction in the exhaust becomes severe, it may prevent the engine from running smoothly o r cause it to stall entirely. This is because the engine cant expel gases effectively.
