Will a Misfire Always Trigger the Malfunction Indicator Light?

[MacSamuel]

A misfire will always trigger the malfunction indicator light. When an engine misfires, symptoms such as unstable idling with noticeable shaking, sluggish acceleration, a significant drop in power, and black smoke from the exhaust pipe will occur. The vehicle owner should visit a repair shop to read the fault codes and have the staff perform corresponding diagnostic and repair work on the car. The causes of engine misfire include: 1. Poor sealing of pistons, cylinder walls, valves, or valve seats leading to low cylinder pressure and misfire; 2. Severe burning of the contacts in the distributor cap of the ignition system causing misfire; 3. Air leaks in the intake system allowing unmetered air to enter the cylinders, resulting in improper engine operation and misfire.
