Solution

1. Preparation

Gather necessary tools and parts.
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 Spark Plugs

Remove the engine cover if applicable using a socket set.
Disconnect the electrical connectors from the ignition coils.
Remove the ignition coils using a socket wrench.
Extract the spark plugs using a spark plug socket.
Inspect the spark plugs for wear or fouling. Replace with OEM specifications if necessary.
Reinstall the spark plugs and ignition coils, ensuring proper torque (typically 15 Nm).
Reconnect electrical connectors and replace the engine cover.

3. Inspect and Replace Engine/Transmission Mounts

Lift the vehicle using a jack and secure it on jack stands.
Locate the engine and transmission mounts.
Inspect mounts for cracks or excessive wear.
Remove the bolts securing the mounts using a socket set.
Replace with OEM mounts, ensuring the correct torque specifications are followed (consult repair manual for exact values).
Lower the vehicle and test for vibrations.

4. Verify Fuel System Integrity

Inspect the fuel injectors for clogs or leaks.
If necessary, clean or replace fuel injectors with OEM parts.
Check the fuel filter for blockages and replace if needed.

5. Check Driveshaft and Tires

Inspect the driveshaft for any visible damage or wear.
If necessary, rebalance the driveshaft or replace any worn components.
Check tire pressure and inspect for uneven wear; rotate or replace tires as needed.
