Solution

1. Preparation

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

2. Inspect and Replace Engine Mounts

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the engine cover if applicable to access engine mounts.
3. Use a socket set to unbolt the engine mounts from the engine and the chassis.
4. Inspect the mounts for cracks, tears, or other signs of damage.
5. If damaged, replace with new engine mounts, ensuring proper alignment.
6. Torque the bolts to the manufacturer's specifications (refer to service manual for exact torque values).

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

Sub-steps:
1. Disconnect the battery to ensure safety.
2. Remove the ignition coil covers if applicable.
3. Carefully disconnect the ignition coils from the spark plugs.
4. Remove the spark plugs using a socket wrench, inspecting for wear or carbon buildup.
5. Replace with new spark plugs that meet manufacturer specifications.
6. Reinstall the ignition coils, ensuring they are seated properly.

4. Clean Throttle Body and Mass Airflow Sensor

Sub-steps:
1. Disconnect the battery again for safety.
2. Remove the air intake duct to access the throttle body.
3. Use throttle body cleaner to clean the throttle plate and body.
4. Remove the mass airflow sensor and clean it with MAF sensor cleaner.
5. Reinstall the throttle body and air intake duct securely.
