2. Lift the engine slightly using a jack and a block of wood for support.
3. Remove the old engine mounts and inspect for cracks or excessive wear.
4. Install new engine mounts and secure them using the bolts, torquing to manufacturer's specifications (typically around 30-45 ft-lbs).

3. Clean Throttle Body

Sub-steps:
1. Remove the air intake duct connected to the throttle body using a screwdriver and socket.
2. Spray throttle body cleaner onto a clean cloth and wipe the throttle body interior.
3. Reconnect the air intake duct securely.

4. Check and Replace Spark Plugs

Sub-steps:
1. Remove the ignition coils by disconnecting the electrical connectors and removing the retaining bolts.
2. Remove the spark plugs with a spark plug socket, inspecting them for wear or carbon buildup.
3. Install new spark plugs, torquing to the manufacturer's specification (typically around 15-20 ft-lbs).
4. Reinstall ignition coils and ensure connections are secure.
