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.
What causes a multiple cylinder misfire in a Hyundai?
