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

Sub-steps:
1. Raise the vehicle using a hydraulic jack and secure it with jack stands.
2. Remove any components obstructing access to the engine mounts (e.g., cover panels).
3. Use a socket set to unbolt the engine mounts from the engine and the chassis.
4. Replace the worn or damaged mounts with new OEM parts, ensuring proper alignment.
5. Torque the new engine mounts to the manufacturer’s specifications.

3. Replace Spark Plugs

Sub-steps:
1. Remove the ignition coil covering to access the spark plugs.
2. Use a spark plug socket to unscrew and remove old spark plugs.
3. Inspect the old plugs for wear; replace them with new plugs of the correct specifications.
4. Reinstall the ignition coils and ensure they are seated correctly.

4. Check and Replace Vacuum Hoses

Sub-steps:
1. Visually inspect all vacuum hoses connected to the intake manifold for cracks or breaks.
2. Replace any damaged hoses with new ones, ensuring a tight fit at all connections.

5. Fuel System Inspection

Sub-steps:
1. Check the fuel filter for clogging and replace if necessary.
2. Test the fuel pump by checking the fuel pressure with a gauge.
3. If low pressure is detected, replace the fuel pump.
