Causes of Engine Misfire.



When the engine misfires, it loses power, can even fail emissions. The cause of the misfire can be electrical or air/fuel related. If the engine is running perfect and all of the cylinders are “firing” that is there is no misfire. 

Once the air fuel ratio inside the combustion chamber in any of the cylinders gets interrupted, the engine will misfire. One cylinder can misfire or more than one cylinder can Misfire depending on the situation. 

To identify the cause of misfire the easiest thing to check is always the secondary electrical circuit. May be problem in both the coil and wire. Also may check total electrical harness and for air/fuel related diagnosis Compression test may be done by compression tester.
