The primary causes of poor idling in a 2002 Mitsubishi Lancer are usually a malfunctioning throttle position sensor, a faulty idle air control valve, or a clogged throttle body valve. The throttle body valve issue is the easiest and cheapest to address; using an approved parts cleaner and a bit of elbow grease should do the trick. If you suspect a problem with the sensor, it is recommended to check for any diagnostic trouble codes (DTCs). These codes can be read using an OBD-II scan tool, which can typically be borrowed for free from most major auto parts stores. Once you retrieve a DTC, you can more accurately pinpoint the cause of the idling problem.
