It’s important to note that the firing order refers to the order in which the spark plugs fire in the engine, and it’s critical to ensure that the spark plugs are wired correctly for the engine to run smoothly. If you’re not sure of the correct firing order, consult the engine’s manual or a qualified mechanic.
