How can you troubleshoot engine misfires in modern vehicles?
A misfire occurs when one or more cylinders in an engine fail to ignite the air-fuel mixture properly, resulting in reduced power, increased emissions, and potential damage to the engine components. Modern vehicles use various electronic systems to monitor and control the engine performance, such as the ignition system, the fuel injection system, the engine control unit (ECU), and the onboard diagnostic system (OBD). Troubleshooting engine misfires in modern vehicles requires a systematic approach that involves identifying the symptoms, scanning the codes, testing the components, and repairing or replacing the faulty parts. In this article, you will learn how to troubleshoot engine misfires in modern vehicles using some basic tools and techniques.
