I have a little confusion about the term Misfire recently. Can somebody here make a exact definition for me? What is Misfire?
The term engine misfires means that there is no combustion in one or more of the engine cylinders. If the engine misfires at certain conditions but not all the time, it's called intermittent misfire. The engine computer or PCM can detect a misfiring cylinder by monitoring the engine speed. Once misfire is detected, the PCM sets the trouble code and turns on the Check Engine light to alert the driver. The OBDII trouble code P0301 means that the cylinder number 1 misfires. The code P0302 stands for cylinder 2 misfires, P0303 is the cylinder number 3 and so on.
