Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool before starting any work.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, pry bar
Sub-steps:
1. Use a socket set to remove the bolts securing the engine mounts to the engine and chassis.
2. Carefully use a pry bar to lift the engine slightly to relieve pressure on the mounts.
3. Remove the old engine mounts and install new mounts, ensuring they are aligned properly.
4. Torque the bolts to the manufacturer’s specifications (refer to service manual for specific torque values).

3. Check and Replace Spark Plugs

Tools Required: Spark plug socket, torque wrench, gap gauge
Sub-steps:
1. Remove the ignition coils by unscrewing the retaining bolts and disconnecting the electrical connectors.
2. Use the spark plug socket to carefully unscrew and remove the spark plugs.
3. Inspect the old spark plugs for wear or carbon buildup and compare with specifications.
4. Install new spark plugs, ensuring proper gap settings using the gap gauge.
5. Torque the new spark plugs to the manufacturer’s specifications.

4. Clean or Replace Air Filter

Tools Required: Screwdriver (if applicable)
Sub-steps:
1. Open the air filter housing and remove the air filter.
