What Is an Engine Misfire?

Engine misfires result from one or more cylinders in an internal combustion engine failing to ignite the air-fuel mixture at the right time. This disruption leads to a loss of power, rough idling, and often a noticeable vibration or shaking in the vehicle. 

The Most Common Causes of a Misfire

Several factors can contribute to a misfire, including faulty spark plugs or ignition coils, clogged fuel injectors, vacuum leaks, or issues with the air-fuel mixture. When spark plugs fail to ignite the fuel-air mixture at the right time, or if there's a disruption in the fuel supply, it leads to incomplete combustion and subsequent misfiring.

A vacuum leak caused by a ruptured hose or gasket, as well as mass airflow sensor failures, can alter the air balance entering the engine. These airflow difficulties can cause misfires by changing the closely controlled air-to-fuel ratio.

How To Prevent a Misfire

Preventing engine misfires involves regular maintenance and attentive care for various components. Adhering to the recommended maintenance schedule for spark plug replacement is crucial, as worn-out or fouled spark plugs are a common cause of misfires. Routine checks and timely replacements of ignition coils, fuel injectors, and the air filter contribute to optimal combustion efficiency. Ensuring a clean fuel system by using quality fuel and additives can also prevent misfires caused by clogged injectors. Regular inspection of the vehicle's sensors, such as the mass airflow sensor and oxygen sensors, helps identify potential issues before they lead to misfires.
