Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Spark Plugs

Sub-steps:
1. Remove the engine cover using a socket set.
2. Disconnect the ignition coils by removing the retaining screws and unplugging the connectors.
3. Remove the old spark plugs using a spark plug socket and ratchet.
4. Inspect the spark plugs for wear; replace them if necessary with OEM specifications (typically NGK or Denso).
5. Install new spark plugs, torque to manufacturer specifications (usually around 13 lb-ft).
6. Reinstall ignition coils and engine cover.

3. Check and Replace Engine Mounts (if necessary)

Sub-steps:
1. Use a jack to support the engine from underneath.
2. Remove any components obstructing access to the engine mounts (e.g., air intake assembly).
3. Inspect the engine mounts for cracks or separation; replace if needed.
4. Remove the bolts securing the damaged engine mount and replace it with a new one, torqueing the bolts to the specified values.
5. Reassemble any removed components.

4. Clean or Replace Idle Air Control Valve (IACV)

Sub-steps:
1. Locate the IACV on the throttle body.
2. Disconnect the electrical connector and remove the mounting screws.
3. Clean the IACV with throttle body cleaner, or replace if it is faulty.
4. Reinstall the IACV and reconnect the electrical connector.
