Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Replace Air Filter

Locate the air intake box.
Open the air intake box and remove the old air filter.
Install the new air filter, ensuring it is seated properly.
Close the air intake box and secure it.

3. Clean Throttle Body

Disconnect the negative battery terminal to prevent electrical shorts.
Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle body.
Ensure the throttle plate moves freely and is not obstructed.
Reinstall the air intake duct and reconnect the negative battery terminal.

4. Replace Spark Plugs

Remove the ignition coil covers if necessary.
Disconnect the ignition coils and remove them from the spark plugs.
Use a spark plug socket to remove the old spark plugs.
Install new spark plugs, ensuring the correct gap is set (refer to manufacturer specifications).
Reinstall the ignition coils and covers.

5. Check Fuel Delivery

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (do not start the engine) and check the fuel pressure reading.
If the pressure is below specifications, inspect the fuel pump and fuel filter for issues.
Replace the fuel pump or filter as necessary.
