- Visually inspect all intake hoses for cracks or disconnections.
- Replace any damaged hoses.

3. Fuel System Repair

Test and Replace Fuel Pump:
- Disconnect the battery.
- Remove the fuel pump access panel (if applicable) or drop the fuel tank.
- Test the fuel pump with a multimeter; replace if faulty.
Replace Fuel Filter:
- Locate the fuel filter and disconnect the fuel lines.
- Replace with a new fuel filter, ensuring proper orientation.

4. Ignition System Maintenance

Inspect and Replace Spark Plugs:
- Remove the ignition coils.
- Check the spark plugs for wear; replace if necessary with OEM parts.
- Reinstall ignition coils, ensuring proper torque specifications.

5. Throttle Body Cleaning

Remove Throttle Body:
- Disconnect the throttle body electrical connector.
- Remove the throttle body bolts and detach the component.
Clean Throttle Body:
- Use throttle body cleaner and a soft brush to remove carbon buildup.
- Reattach the throttle body and reconnect the electrical connector.
