Solution

1. Preparation

Gather the necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shorts.
Ensure the engine is cool before beginning work.

2. Inspect and Replace Engine Mounts

Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Locate the engine mounts (typically on either side of the engine).
3. Visually inspect for cracks, tears, or signs of fluid leakage.
4. If damaged, remove the bolts securing the mounts using a socket set.
5. Replace with new engine mounts, ensuring proper alignment.
6. Torque the mount bolts to the manufacturer's specifications (check torque values in the service manual).

3. Check and Replace Spark Plugs and Ignition Coils

Sub-steps:
1. Remove any necessary engine covers to access the spark plugs.
2. Disconnect ignition coil connectors and remove the coils using a socket set.
3. Remove old spark plugs using a spark plug socket.
4. Inspect the spark plugs for wear and replace if necessary (use OEM recommended types).
5. Reinstall new spark plugs and ignition coils, ensuring proper torque specifications.

4. Clean Throttle Body

Sub-steps:
1. Remove the air intake duct leading to the throttle body.
2. Use throttle body cleaner and a soft brush to remove carbon buildup.
3. Clean the throttle plate and surrounding areas thoroughly.
4. Reattach the air intake duct securely.
