What would cause a misfire in cylinder 6?
P0306 indicates that cylinder number 6 is experiencing misfires. A misfire occurs when an insufficient amount of fuel is burning in a cylinder. A misfire from one or more cylinders can be caused by many reasons from a faulty ignition system, fuel system, or internal engine failure.
What does a 6th cylinder misfire mean?
When cylinder number 6 misfires, it means that the air and fuel mixture in that cylinder has failed to ignite. As a result, the engine’s speed fluctuates, causing the crankshaft position sensor signal to vary. The ECM detects this and reports a misfire in the specific cylinder.
What causes a slight misfire?
The most common causes of misfires are worn, improperly installed, and mishandled spark plugs, malfunctioning ignition coils, carbon tracking, faulty spark plug wires and vacuum leaks. Spark plugs deliver the electric current from the ignition system to the combustion chamber, igniting the compressed fuel/air mixture.
