Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety.

2. Inspect Engine Mounts

Lift the vehicle securely using a jack and jack stands.
Remove any components obstructing access to the engine mounts.
Visually inspect each engine mount for cracks, tears, or excessive wear.
If damaged, proceed to replace the engine mounts.

3. Replace Spark Plugs and Ignition Coils (if necessary)

Remove the engine cover to access the ignition coils and spark plugs.
Disconnect the electrical connectors from the ignition coils.
Unscrew and remove the ignition coils using a socket set.
Remove old spark plugs using a spark plug socket.
Install new spark plugs, tightening them to the manufacturer's specified torque (typically around 13-15 lb-ft).
Reinstall ignition coils and reconnect electrical connectors.

4. Clean or Replace Fuel Injectors

Remove the fuel rail to access the fuel injectors (ensure fuel pressure is relieved first).
Inspect fuel injectors for clogs; clean using a specialized injector cleaning kit if they are dirty.
Replace any damaged or faulty fuel injectors with new ones.

5. Check Air Intake and Vacuum Hoses

Visually inspect all air intake hoses and vacuum lines for cracks or leaks.
Replace any damaged hoses with OEM parts to ensure proper sealing.
Reassemble any components removed during inspection.

6. Throttle Body Cleaning

Locate the throttle body and remove the intake ducting.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
Reinstall the intake ducting securely.
