Solution

1. Preparation

Tools Required: OBD-II scanner, air filter, fuel pressure gauge, throttle body cleaner, socket set, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is cool before starting the work.
Disconnect the battery to ensure safety while working on electrical components.

2. Replace Air Filter

Remove the engine cover if applicable.
Disconnect the clips or screws holding the air filter housing.
Carefully remove the old air filter and replace it with a new one.
Reassemble the air filter housing and secure it properly.

3. Clean Throttle Body

Locate the throttle body assembly on the intake manifold.
Remove the intake duct connected to the throttle body by loosening the clamps.
Use throttle body cleaner and a soft cloth to clean the internal surfaces of the throttle body.
Reinstall the intake duct and secure it.

4. Inspect and Replace Spark Plugs

Remove the ignition coil or spark plug cover as necessary.
Using a spark plug socket, carefully remove each spark plug.
Inspect the spark plugs for wear or fouling and replace them if needed.
Reinstall the new spark plugs and secure them to the manufacturer’s specified torque.

5. Check and Replace Fuel Filter (if applicable)

Locate the fuel filter, typically found along the fuel line or within the fuel tank.
Relieve fuel system pressure using the appropriate procedure (consult service manual).
Disconnect fuel lines from the filter and replace the old filter with a new one.
Reconnect the fuel lines and ensure there are no leaks.
