Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, vacuum gauge.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Engine Mounts

Locate the engine mounts; they are usually found securing the engine to the vehicle chassis.
Sub-steps:
1. Use a socket set to remove the bolts securing the engine mounts.
2. Carefully lift the engine slightly using an engine hoist or jack to relieve pressure on the mounts.
3. Inspect the mounts for signs of cracks or deterioration.
4. If damaged, install new engine mounts by reversing the removal process.
5. Torque the bolts to the manufacturer’s specifications (consult the service manual for exact torque values).

3. Check and Replace Spark Plugs

Remove the ignition coils to access the spark plugs.
Sub-steps:
1. Use a spark plug socket to carefully remove the spark plugs.
2. Inspect the spark plugs for wear or carbon buildup.
3. If necessary, replace with new spark plugs that meet OEM specifications.
4. Reinstall the ignition coils and ensure they are secured.

4. Inspect Fuel Delivery System

Check the fuel pump and fuel injectors for proper operation.
Sub-steps:
1. Use a fuel pressure gauge to check the fuel pressure (refer to service manual for specifications).
2. If low pressure is detected, inspect and possibly replace the fuel pump.
3. Clean or replace fuel injectors if they are found to be clogged or malfunctioning.

5. Check for Vacuum Leaks

Inspect hoses and connections in the intake system for leaks.
Sub-steps:
1. Use a vacuum gauge to check for proper readings.
2. Replace any damaged hoses or seals to ensure a tight fit.
