Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts during the repair.

2. Inspect and Replace Engine Mounts (if necessary)

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the engine mounts, typically found at the corners of the engine.
3. Using a socket set, remove the bolts securing the engine mount to the engine and the frame.
4. Carefully lift the engine slightly to relieve pressure on the mount.
5. Remove the old mount and install the new mount in reverse order.
6. Torque the bolts to the manufacturer's specifications (usually around 30-50 ft-lbs, check service manual for exact specs).

3. Replace Spark Plugs (if necessary)

Sub-steps:
1. Remove the ignition coils by unscrewing the bolts and disconnecting the wiring harness.
2. Use a spark plug socket to remove the old spark plugs.
3. Inspect the old plugs for wear; replace with new plugs as necessary.
4. Install the new spark plugs, tightening them to the specified torque (typically 13-16 ft-lbs).
5. Reinstall the ignition coils and reconnect the wiring harness.

4. Inspect and Repair Air Intake System (if necessary)

Sub-steps:
1. Remove the air intake duct by loosening the clamps and disconnecting any sensors.
2. Inspect the air filter for cleanliness; replace if dirty.
3. Check for any cracks or loose connections in the intake ducts.
4. Reassemble the intake system ensuring all connections are tight.
