- Replace Damaged Components: Use appropriate replacement parts for damaged fuel lines, seals, or injectors.
- Tighten Connections: For loose connections, ensure they are secured properly.

3. Replace Faulty Fuel Injectors (if applicable)

Sub-steps:
- Remove Engine Cover (if necessary): Use a socket set to remove the cover.
- Disconnect Fuel Lines: Use a line wrench to carefully disconnect fuel lines from the injectors.
- Remove Injectors: Unbolt the fuel rail and carefully remove the injectors.
- Install New Injectors: Apply a small amount of engine oil to the O-rings of the new injectors and install them.
- Reassemble: Reattach the fuel rail and reconnect the fuel lines, ensuring a tight fit.
