Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety.
Allow the engine to cool down before beginning the repair process.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, jack and jack stands
Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Locate the engine mounts (typically two or three mounts).
3. Use a socket set to remove the bolts securing the mount to the engine and frame.
4. Inspect the mount for cracks or separation of the rubber from the metal.
5. Replace any worn or damaged mounts with new ones, ensuring proper alignment.
6. Torque the bolts to the manufacturer’s specifications (check repair manual for specific torque values).
7. Reconnect the battery.

3. Address Vacuum Leaks

Tools Required: Vacuum gauge, hose clamps
Sub-steps:
1. Visually inspect all vacuum hoses for cracks or disconnections.
2. If a leak is suspected, use a vacuum gauge to check the vacuum pressure in the intake manifold.
3. Replace any damaged hoses and secure all connections with hose clamps.
4. Clear any trouble codes and test idle quality again.

4. Check Ignition System

Tools Required: Spark plug socket, multimeter
Sub-steps:
1. Remove the spark plugs using a spark plug socket.
2. Inspect spark plugs for wear and replace if necessary (replace with OEM specified type).
3. Test ignition coils using a multimeter to ensure they are functioning properly.
4. Replace any faulty ignition coils.
5. Reassemble all components and clear any error codes.
