Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working.
Ensure the engine is cool before performing any inspections.

2. Clean the Throttle Body

Remove the air intake duct connected to the throttle body.
- Tools required: Socket set
- Safety warning: Ensure the engine is off and cool.
Use a throttle body cleaner and a soft cloth or brush to clean the throttle plate and surrounding area.
Reinstall the intake duct securely.

3. Replace Fuel Filter (if applicable)

Locate the fuel filter; it may be integrated with the fuel pump in the fuel tank.
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter (use caution as fuel may spill).
Remove the old fuel filter and replace it with a new one.
Reconnect fuel lines and fuse, then turn the ignition to the "ON" position to prime the fuel system.

4. Inspect and Replace Spark Plugs

Remove the ignition coils from the engine.
- Tools required: Socket set, torque wrench
Remove the spark plugs using a spark plug socket.
Inspect the old spark plugs for wear or fouling; replace as necessary with OEM specifications.
Torque new spark plugs to manufacturer specifications and reinstall the ignition coils.
