Here's why it's important to know the exact year and model:
* Different distributor cap designs: Earlier models may have different distributor cap designs with different wiring layouts.
* Engine configuration: Even within the same year, different engine configurations (like V6 vs. V8) can have different wiring orders.
To determine the correct firing order, you'll need:
1. Year and Model: Provide the specific year, make, and model of your Chevrolet vehicle.
2. Engine Code: Locate the engine code on the engine block (usually stamped or etched).
Once you have this information, you can:
* Consult a repair manual: Your vehicle's repair manual will provide a detailed wiring diagram for your specific engine configuration.
* Use an online resource: Many online resources, like car repair websites and forums, offer detailed information on spark plug firing order.
