Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Allow the engine to cool down before starting work.

2. Inspect and Replace Engine Mounts (if necessary)

• Tools Required: Socket set, torque wrench, jack stands
• Sub-steps:
  1. Lift the vehicle using a jack and secure it with jack stands.
  2. Locate the engine mounts (typically found on the front and rear of the engine).
  3. Visually inspect the mounts for cracks, tears, or excessive wear.
  4. If damaged, remove the bolts securing the mount to the engine and the chassis.
  5. Replace with new engine mounts, ensuring they are properly aligned.
  6. Torque the bolts to the manufacturer’s specifications.

  3. Use throttle body cleaner and a rag to clean the throttle plate and housing.
  4. If heavily fouled or malfunctioning, replace the throttle body with a new unit.
  5. Reassemble all components and ensure secure connections.

4. Check and Replace Spark Plugs and Ignition Coils (if necessary)

• Tools Required: Socket set, torque wrench
• Sub-steps:
  1. Remove the engine cover (if applicable) to access the spark plugs.
  2. Disconnect the ignition coil connectors and remove the coils.
  3. Extract the spark plugs using a socket wrench.
