To find out which engine you have:
1. Check your vehicle's documentation: Your owner's manual will definitively state the engine size.
2. Look at the engine itself: The engine displacement (3.1L or 3.4L) is usually cast into a visible part of the engine block.
3. Check your vehicle's identification number (VIN): You can decode the VIN to determine the engine.
Once you know the engine size, use the corresponding firing order above. Remember that this information is for general guidance; always consult your owner's manual for the most accurate information specific to your vehicle.
