Hook it up to an OBD-II scanner and check for a miss if it is obd-II compliant.
OBD II DIAGNOSTIC TROUBLE CODES Introduction To comply with On-Board Diagnostics Second Generation (OBD II) regulations, the Powertrain Control Module (PCM) is equipped with software designed to allow it to monitor vehicle emission control systems and components. Once the ignition is turned on or the engine is started, and certain test conditions are met, the PCM runs a series of monitors to test the emission control systems and components. Test conditions include different inputs such as time since startup, run-time, engine speed and temperature, transaxle gear position, and the engine open or closed loop status. Once the monitor is started, the control module attempts to run it to completion. If a particular monitor fails a test, a code is set and operating conditions at that time are recorded in memory. If the same component or system fails twice in succession, the Malfunction Indicator Lamp (MIL) is activated. Monitors are divided into 2 types: Main Monitors and the Comprehensive Component Monitors.
