A blinking malfunction indicator lamp (MIL), commonly known as a check engine light, signals a serious issue demanding immediate attention. This behavior indicates a severe engine misfire is occurring. A misfire means one or more of the engine’s cylinders are not firing correctly, resulting in unburnt fuel entering the exhaust system.
The immediate concern is catalytic converter damage. Unburnt fuel in the exhaust significantly elevates the temperature of the catalytic converter, potentially leading to melting or other irreversible damage. Catalytic converters are expensive to replace, making preventative action crucial. Furthermore, a severe misfire can contribute to increased emissions and reduced fuel efficiency.
