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 issues during repair.

2. Inspect and Replace Air Filter

Remove the air filter cover using a socket set.
Take out the old air filter and inspect it for dirt and blockage.
Install a new air filter, ensuring it fits snugly.
Reattach the air filter cover and secure it.

3. Clean the Throttle Body

Remove the intake duct connected to the throttle body using a socket set.
Use throttle body cleaner and a soft brush to clean the throttle body.
Ensure the throttle plate moves freely without any obstruction.
Reattach the intake duct securely.

4. Test and Replace Spark Plugs (if necessary)

Remove the ignition coil assemblies using a socket set.
Unscrew the old spark plugs using a spark plug socket.
Inspect the spark plugs for wear and replace them if necessary with OEM specifications.
Reinstall the ignition coils and ensure they are seated correctly.

5. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail test port.
Start the engine and check the fuel pressure against the manufacturer’s specifications.
If pressure is low, inspect the fuel pump and fuel filter for blockages or failure.
Replace the fuel filter if it is clogged, and consider replacing the fuel pump if necessary.
