This means that the cylinders fire in that order, starting with cylinder #1 at the front of the engine and ending with cylinder #2 at the rear.
Here's a breakdown of the cylinder arrangement:
* Bank 1: Cylinders 1, 3, 5, 7
* Bank 2: Cylinders 2, 4, 6, 8
Remember that this is a general firing order for most 2002 Lincoln LS V8 engines. However, it's always a good idea to double-check your specific engine model and year to ensure accuracy. You can find this information on the engine block or in your owner's manual.
