Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shock while working on the vehicle.

2. Clean or Replace the Air Filter

Remove the air intake duct by loosening the clamps with a screwdriver.
Take out the air filter and inspect it for dirt and damage.
If clogged, either clean it if reusable or replace it with a new filter.
Reassemble the air intake duct securely.

3. Check and Replace Spark Plugs

Remove the ignition coils by unscrewing them from the engine.
Unscrew the old spark plugs using a spark plug socket.
Inspect the spark plugs for wear; replace them if necessary with OEM specifications.
Reinstall the ignition coils and ensure they are securely fastened.

4. Inspect and Clean the Throttle Body

Remove the throttle body from the intake manifold by unscrewing the bolts.
Use throttle body cleaner and a soft brush to clean any carbon buildup.
Reinstall the throttle body, ensuring a proper seal with a new gasket if necessary.

5. Check Fuel Pressure

Attach the fuel pressure gauge to the fuel rail service port.
Turn the ignition to the ON position (do not start the engine) and check if the pressure is within manufacturer specifications.
If the pressure is low, inspect and replace the fuel pump if necessary.
