Will the car's misfire trigger the malfunction indicator light?

[EmiliaLynn]

Car misfire will trigger the malfunction indicator light, usually a yellow warning light. After engine misfire occurs, the vehicle will experience increased fuel consumption, black smoke emission, weak acceleration, severe vibration, and louder engine noise. It's also prone to stalling. The method to diagnose misfire is relatively simple: sequentially disconnect spark plug wires or fuel injector connectors while the engine is running. For normally functioning cylinders, cutting off spark or fuel will cause obvious engine reaction, while non-functioning cylinders will show almost no change in engine operation. Another method is to use an infrared thermometer to measure exhaust pipe temperature - the exhaust temperature of non-firing cylinders will be significantly lower than that of firing cylinders.
