How do I know if my firing order is correct? (video)
How does the firing order work?
The firing order of an internal combustion engine is the sequence of ignition for the cylinders. In a spark-ignition (e.g. gasoline/petrol) engine, the firing order corresponds to the order in which the spark plugs are operated. Firing order affects the vibration, sound, and evenness of power output from the engine. via
