Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to prevent electrical shorts.
  • Allow the engine to cool down completely before starting work.
2. Remove Ignition Coils
  • Sub-steps:
    • Remove the engine cover if necessary, using a socket set.
    • Disconnect the electrical connector from each ignition coil.
    • Remove the bolts securing the ignition coils, then carefully pull them out.
3. Remove Spark Plugs
  • Sub-steps:
    • Use a spark plug socket and ratchet to unscrew each spark plug from the cylinder head.
    • Keep track of which spark plug came from which cylinder for reinstallation.
4. Inspect and Replace Spark Plugs
  • Sub-steps:
    • Inspect the old spark plugs for wear, carbon deposits, or damage.
    • Set the gap on new spark plugs to the manufacturer's specifications using a feeler gauge.
    • Install the new spark plugs into the cylinder head by hand, then torque to the specified value (usually 13-15 lb-ft for Toyota).
5. Reinstall Ignition Coils
  • Sub-steps:
    • Carefully place the ignition coils back into their respective positions.
    • Tighten the bolts to secure the ignition coils.
    • Reconnect the electrical connectors to each coil.
6. Final Checks
