Engine misfire	Engine system fault Ignition system Crankshaft position sensor Fuel system Charge air system Mass air flow sensor Fuel level low Spark plugs fouled/worn Crankshaft position sensor incorrectly installed Crankshaft position sensor reluctor ring runout or air gap out of tolerance Poor fuel quality Incorrect fuel specification Incorrect grade or blend Contaminated fuel Unauthorised additives Driveline imbalance Driveline components excessively worn Wheel/tire imbalance Cylinder compression(s) too low Catalytic converter blocked or damaged Engine mount damaged Transmission mount damaged Primary drive belt components incorrectly installed Fuel injector(s) contaminated/blocked	NOTE: The misfire monitor operates continuously and is designed to detect levels of misfire that can cause either thermal damage to the catalyst or excessive tailpipe emissions. Determination of a misfire is made by analysis of changes in crankshaft speed, since a misfire will cause a fall in speed. Essentially the monitor determines the time taken for the crankshaft to move through 180° (4 cylinder engines only) for the current firing event and compares that to the time taken for the previous firing event. If the time taken for the "current" firing is greater than the previous firing, then a misfire is judged to have occurred. Using the manufacturer approved diagnostic system, check the engine control module for related DTCs and refer to the relevant DTC index Check the fuel level Check the spark plugs for cracks, damage, carbon build up, wet fouling, electrode gap too large/small, center electrode condition, ground electrode condition Check the installation of the crankshaft position sensor Check the installation of the crankshaft position sensor reluctor ring Drain and refuel with new fuel Check driveline for debris around rotating components Check driveline for excessive wear or backlash Check wheels and tires for snow or mud packing and correct balance Refer to the relevant section of the service information and test the cylinder compressions Check the catalytic converter for blockage or damage Check the engine mounts for damage Check the transmission mounts for damage Check the installation of the primary drive belt components Check the fuel injectors for contamination or blockages
