- Tools: Socket set, screwdrivers.
- Carefully disconnect the air intake duct and remove the housing.
Inspect and replace the air filter:
- If dirty or clogged, replace with a new OEM air filter.
- Reassemble the air intake system securely.

3. Fuel System Inspection

Check fuel pressure:
- Connect the fuel pressure gauge to the fuel rail.
- Start the engine and ensure the pressure meets manufacturer specifications.
Replace the fuel filter (if applicable):
- If pressure is low, replace the fuel filter according to the owner's manual.
- Reconnect fuel lines and ensure all fittings are secure.

4. Throttle Body Cleaning

Remove the throttle body:
- Disconnect the battery, then unplug the throttle position sensor.
- Remove the throttle body using a socket set.
Clean the throttle body:
- Use throttle body cleaner and a soft cloth to remove carbon buildup.
- Reinstall the throttle body and reconnect all components.

5. Ignition System Check

Inspect spark plugs and ignition coils:
- Remove spark plugs with a spark plug socket.
- Check for wear or damage; replace if necessary.
Test ignition coils:
- Use a multimeter to check the resistance of each coil.
- Replace any faulty coils.
