Sub-steps:
1. Remove the engine cover if applicable.
2. Locate the spark plugs and carefully disconnect the ignition coils.
3. Remove the spark plugs using a socket wrench and inspect for wear.
4. If worn or damaged, replace with OEM-spec spark plugs.
5. Install new spark plugs and torque to manufacturer specifications (usually around 13-15 ft-lbs).
6. Reconnect ignition coils and engine cover.

3. Inspect and Replace Engine Mounts

Sub-steps:
1. Visually inspect engine mounts for cracks or excessive wear.
2. If damaged, support the engine with a jack and remove the old mounts.
3. Install new engine mounts, ensuring proper alignment.
4. Torque to manufacturer specifications (check service manual for specific values).
