Tools Required: Throttle body cleaner, soft cloth, screwdriver
Remove the air intake duct connected to the throttle body.
Spray throttle body cleaner into the throttle body while opening the throttle plate manually.
Wipe clean with a soft cloth to remove carbon buildup.
Reattach the air intake duct securely.

4. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench, new spark plugs
Remove the ignition coils by unscrewing them from the engine.
Take out the old spark plugs using a socket wrench.
Inspect the spark plugs for wear and replace them if necessary, ensuring the correct gap.
Torque the new spark plugs to the manufacturer's specifications (typically around 13 lb-ft).
Reinstall the ignition coils, securing them properly.

5. Check Fuel System

Tools Required: Fuel pressure gauge, basic hand tools
Connect a fuel pressure gauge to the fuel rail.
Start the engine and check for proper fuel pressure as specified by the manufacturer.
