This means the spark plugs fire in that order, starting with cylinder 1 and ending with cylinder 2.
It's important to remember that this applies to the majority of 5.7L Vortec engines produced in 2000. However, there might be variations depending on the specific model and application.
To confirm the exact firing order for your specific vehicle, you can check the following resources:
* Owner's Manual: Your owner's manual should have the firing order listed.
* Engine ID Tag: The engine ID tag, typically located on the passenger side of the engine block, may contain the firing order.
* Online Resources: Several websites and forums dedicated to Chevrolet vehicles can provide information on firing orders.
Always consult your owner's manual or a trusted mechanic for specific information regarding your vehicle.
