Firing Order: 1-8-4-3-6-5-7-2
Understanding the Firing Order:
1. Numbered Cylinders: Imagine your engine has eight cylinders, labeled 1 through 8 starting from the front of the engine (passenger side) and going towards the rear (driver's side).
2. Sequence: The firing order indicates the sequence in which the spark plugs ignite, causing combustion within each cylinder. For example, cylinder 1 ignites first, then cylinder 8, then cylinder 4, and so on.
How to Use the Firing Order Diagram:
