Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative terminal of the battery to ensure safety during work.
Allow the engine to cool down before starting any inspections.

2. Replace Air Filter

Locate the air filter housing.
Remove the clips or screws securing the housing.
Take out the old air filter and inspect for damage.
Insert a new air filter, ensuring it fits snugly.
Re-secure the housing with clips or screws.

3. Clean Throttle Body

Remove the intake duct from the throttle body.
Use a throttle body cleaner and a soft cloth to clean the interior of the throttle body.
Ensure the throttle plate operates smoothly after cleaning.
Reattach the intake duct securely.

4. Test and Replace Fuel Pump (if necessary)

Connect a fuel pressure gauge to the fuel rail.
Start the engine and check the pressure reading against the manufacturer specifications.
If pressure is low, disconnect the fuel lines and remove the fuel pump from the tank.
Install a new fuel pump, ensuring proper placement and sealing.
Reconnect fuel lines and check for leaks.

5. Inspect and Replace Ignition Components

Remove the ignition coils from the spark plugs.
Inspect and replace damaged spark plugs if needed.
Test ignition coils with a multimeter; replace any that are faulty.
Reinstall the ignition coils and ensure they are seated properly.
