How do you diagnose engine misfire?
The PCM can detect when a cylinder decelerates (an indication of a misfire), store a Diagnostic Trouble Code (DTC) in memory, and turn on the Check Engine Light. Some car computers detect misfires by measuring electrical activity [ionization] at the spark plug electrodes.
Can bad spark plugs cause cylinder misfire?
The most common cause of an engine misfire when accelerating is worn-out spark plugs. When spark plugs are suffering from excessive wear, they don’t ignite the fuel in the piston cylinder when they are supposed to. This can also be caused by fouled spark plugs, a cracked distributor cap, or bad spark plug wires.
