Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the engine is cool.
  • Disconnect the battery to prevent electrical shock.
2. Inspect and Replace Engine Mounts

  1. Locate Engine Mounts:

    • Identify the engine mounts (typically there are two or three).
    • Use a socket set to remove the bolts securing the mounts.

  2. Check for Damage:

    • Inspect the rubber portions of the mounts for cracks or separation.
    • If damaged, proceed to replace them.

  3. Replace Engine Mounts:

    • Position the new engine mount in place.
    • Torque bolts to manufacturer specifications (usually around 40-60 Nm, check service manual for exact values).
3. Clean or Replace Ignition Components

  1. Remove Ignition Coils:

    • Disconnect the wiring harness from each ignition coil.
    • Unbolt and remove the coils from the spark plugs.

  2. Inspect Spark Plugs:

    • Remove spark plugs using a spark plug socket.
    • Check for wear or fouling; replace if necessary with OEM specifications (typically NGK or Bosch).

  3. Reinstall Ignition Components:

    • Reinstall clean or new spark plugs, torque to manufacturer specifications (usually 20-30 Nm).
    • Reinstall ignition coils and reconnect wiring harnesses.
4. Clean Throttle Body and Idle Air Control Valve

  1. Access Throttle Body:

    • Remove the intake duct to access the throttle body.
    • Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.

  2. Inspect Idle Air Control Valve:

    • If applicable, remove the idle air control valve.
    • Clean with throttle body cleaner and ensure it moves freely.

  3. Reassemble:

    • Reattach the intake duct and ensure all connections are secure.
