Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, vacuum gauge.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Address Engine Mounts

Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Remove any components obstructing access to the engine mounts (e.g., air intake, covers).
3. Inspect each engine mount for visible damage or excessive wear.
4. If damaged, remove the old mount by unbolting it from the engine and chassis.
5. Install the new engine mount, tightening bolts to the manufacturer’s specified torque (typically around 30-40 Nm).
6. Reassemble any removed components.

3. Replace Spark Plugs and Ignition Coils

Sub-steps:
1. Remove the engine cover if necessary to access the ignition coils.
2. Disconnect the electrical connectors from the ignition coils.
3. Unbolt and remove the ignition coils from the spark plugs.
4. Remove old spark plugs using a spark plug socket.
5. Install new spark plugs (gapping them according to specifications, generally 0.7-0.8 mm).
6. Reinstall ignition coils and reconnect electrical connectors.

4. Clean Throttle Body

Sub-steps:
1. Disconnect the throttle body electrical connector.
2. Remove the intake duct connected to the throttle body.
3. Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
4. Reinstall the intake duct and throttle body connector.
