Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety.

2. Inspect and Replace Spark Plugs

Remove the ignition coils using a socket set.
Extract the spark plugs with a spark plug socket.
Inspect spark plugs for wear; replace if necessary with OEM parts.
Reinstall spark plugs and ignition coils, ensuring proper torque (typically 15 Nm).

3. Fuel System Inspection

Locate the fuel filter and check for clogs; replace if necessary.
Test the fuel pump operation using a fuel pressure gauge to ensure it meets manufacturer specifications (usually around 50-60 psi).
If faulty, replace the fuel pump as needed.

4. Throttle Body Cleaning

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean carbon buildup.
Reassemble the intake and ensure all connections are secure.

5. Transmission Fluid Check and Replacement

Check the transmission fluid level using the dipstick.
If low, add the correct type of fluid (check owner’s manual for specifications).
If fluid is dark or has a burnt odor, consider a transmission fluid change.

6. Engine Mount Inspection

Visually inspect engine mounts for cracks or excessive wear.
If damaged, replace engine mounts with OEM replacements.
