  • Inspect old plugs for wear and replace with new ones if necessary, ensuring the correct gap.
  • Reinstall the spark plug wires in the correct order.

5. Check and Adjust Tire Pressure

  • Use a tire pressure gauge to check the tire pressure of all tires.
  • Inflate or deflate tires to the manufacturer’s recommended pressure.
  • Inspect for uneven wear or alignment issues and address as needed.
