What happens when a catalytic converter is misfiring?

When a cylinder misfires, it can cause a cylinder’s worth of hot, unburnt to fuel enter the catalytic converter, melt the ceramic material inside. As the inside of the catalytic converter heats up it can start to break apart, plugging the exhaust, which causes problems to keep cascading. But catalytic converters aren’t the only concern.

Is it OK to drive an engine that is misfiring?

Instead from that, misfires can damage other sensors in the engine like the O2 sensors. So, I would never recommend driving an engine that is misfiring for any long distances. Short distances to your mechanic workshop without putting a load on the engine is fine, but do not ignore the misfires and keep driving.
