To find the correct firing order, you must know the engine size and type (e.g., 2.5L 4-cylinder, 3.1L V6, 5.7L V8, etc.). Then, you can:
1. Check your owner's manual: This is the most reliable source.
2. Look under the hood: Sometimes the firing order is stamped on a sticker or plate somewhere in the engine bay.
3. Use a reliable online resource: Websites like Haynes or Chilton manuals often have this information, but make absolutely sure you're selecting the correct year, make, *and model* of your Chevy and the specific engine.
Without knowing the engine specifics, I cannot provide the firing order.
