A vehicle may surge while driving due to several factors, including fuel delivery issues, such as a clogged fuel filter or failing fuel pump, which can disrupt the engine's power supply. Additionally, problems with the ignition system, like faulty spark plugs or ignition coils, can lead to inconsistent engine performance. Electrical issues, such as a malfunctioning sensor (like the mass airflow or throttle position sensor), can also cause surging by sending incorrect data to the engine control unit. Lastly, transmission problems may lead to erratic power delivery, contributing to the sensation of surging.
