Common Causes of an Engine Misfire
An engine misfire can occur for a variety of reasons, including:
- Faulty spark plugs - Spark plugs provided the spark that ignites the fuel in the engine's cylinders. If a spark plug is worn out or malfunctioning, an engine misfire can occur..
- Malfunctioning fuel injector - Fuel injectors are responsible for delivering fuel to the engine's cylinders. If a fuel injector is clogged or malfunctioning, it can cause an engine misfire.
- Clogged air filter - If the air filter is clogged, airflow to the engine is restricted, which can lead to an engine misfire.
- Problem with the ignition system - The ignition system provides the spark that ignites the fuel in the engine's cylinders. If there is a problem here, it can cause an engine misfire.
- Wiring issues - Problems with the wiring in the car can cause an engine misfire.
- Vacuum leak - A vacuum leak can allow air to enter the engine, disrupting the air-fuel ratio.
- Failed sensor - If a sensor, such as the oxygen sensor, fails, it can cause an engine misfire.
