Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Check and Replace Air Filter

Locate the air filter housing.
Open the housing and remove the old air filter.
Inspect for dirt and debris; replace with a new filter if necessary.
Reassemble the housing securely.

3. Test and Replace Fuel Pump (if necessary)

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the ON position (do not start) and check pressure against specifications.
If pressure is low, locate the fuel pump in the fuel tank.
Remove the fuel tank (drain if necessary), disconnect the fuel lines, and replace the pump.
Reassemble and reconnect all components, ensuring there are no leaks.

4. Clean Throttle Body

Remove the intake duct to access the throttle body.
Use throttle body cleaner and a soft brush to clean carbon buildup.
Reinstall the intake duct securely.

5. Inspect and Replace Spark Plugs

Remove the ignition coil cover (if applicable).
Disconnect the ignition coils and remove the spark plugs using a socket set.
Inspect for wear and replace with new spark plugs according to specifications.
Reinstall coils and cover.
