Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, pry bar
Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Locate the engine mounts (usually at the front and rear of the engine).
3. Use the socket set to remove the bolts securing the engine mounts to the engine and chassis.
4. Inspect the mounts for cracks, tears, or excessive wear. Replace if necessary.
5. Position new mounts in place and secure them with bolts. Torque bolts to the manufacturer's specification.

3. Replace Spark Plugs and Ignition Coils

Tools Required: Socket set, torque wrench, dielectric grease
Sub-steps:
1. Remove the engine cover, if applicable, to access the spark plugs.
2. Disconnect the ignition coil connectors and remove the coils using the socket set.
3. Remove the spark plugs using a spark plug socket.
4. Inspect the old spark plugs for wear and carbon buildup, and replace with new plugs.
5. Apply dielectric grease to the ignition coil boots before reinstallation.
6. Reinstall the ignition coils and reconnect the connectors, ensuring they are secure.

4. Check and Clean the Air Intake System

Tools Required: Screwdriver set, cleaning spray (MAF cleaner), soft cloth
Sub-steps:
1. Disconnect the air intake duct from the throttle body.
2. Inspect the air filter and replace if dirty.
3. Use MAF cleaner to clean the mass airflow sensor if applicable.
4. Reassemble the air intake system securely.
