Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, pry bar
Sub-steps:
1. Locate the engine mounts; these are typically found at the front and rear of the engine.
2. Use a socket set to remove the bolts securing the engine mounts.
3. Carefully lift the engine slightly using a jack and a block of wood to avoid damage.
4. Remove the old engine mounts and install new ones, ensuring proper alignment.
5. Torque the bolts to manufacturer specifications, usually around 50-60 ft-lbs (check specific values for your model).

3. Clean or Replace Spark Plugs and Ignition Coils

Tools Required: Spark plug socket, torque wrench, dielectric grease
Sub-steps:
1. Remove the ignition coil cover, if applicable, to access the spark plugs.
2. Disconnect the electrical connector from each ignition coil.
3. Use a spark plug socket to remove the spark plugs; inspect them for wear or fouling.
4. Replace old plugs with new ones, applying dielectric grease to the threads.
5. Reinstall ignition coils and reconnect electrical connectors.

4. Check and Clean Throttle Body

Tools Required: Throttle body cleaner, soft cloth, screwdriver
Sub-steps:
1. Disconnect the air intake duct to access the throttle body.
2. Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
3. Ensure the throttle plate opens and closes smoothly.
4. Reconnect the air intake duct securely.
