However, you MUST verify this with your specific Tahoe's engine. Different engines (even within the same year and model) might have variations. The best way to ensure accuracy is to:
* Check your owner's manual: This is the most reliable source.
* Look for a diagram under the hood: Many vehicles have a sticker or decal showing the firing order near the engine.
* Consult a repair manual specific to your Tahoe's year and engine: Chilton's or Haynes manuals are good options.
Wiring the spark plugs incorrectly can severely damage your engine. If you are unsure, seek professional help from a mechanic.
