Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, compression tester, vacuum gauge, torque wrench, multimeter.
Ensure the vehicle is parked on a level surface and the engine is cool before starting any work.

2. Replace Engine Mounts (if damaged)

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove any components obstructing access to the engine mounts (e.g., air intake duct).
3. Support the engine with a jack under the oil pan or transmission.
4. Remove bolts securing the damaged engine mount to the engine and chassis.
5. Install the new engine mount and torque bolts to manufacturer specifications (usually around 45-60 ft-lbs).
6. Reinstall any removed components.

3. Repair or Replace Vacuum Leaks

Sub-steps:
1. Use a vacuum gauge to check for proper vacuum levels.
2. Inspect all vacuum hoses visually for cracks or disconnections.
3. Replace any damaged hoses with OEM or high-quality aftermarket parts.
4. Recheck vacuum levels after repairs.

4. Replace Spark Plugs and Test Ignition Coils

Sub-steps:
1. Remove the engine cover (if applicable).
2. Disconnect the ignition coils and remove them using a socket set.
3. Remove the old spark plugs with a spark plug socket.
4. Install new spark plugs, ensuring they are gapped according to specifications (usually around 0.050 in).
5. Reinstall ignition coils and reconnect wiring.
