2. Remove the fuel rail by unscrewing the mounting bolts.
3. Carefully pull out the faulty injector(s) and replace with new ones.
4. Reassemble the fuel rail and reconnect the electrical connectors.

4. Inspect and Repair EVAP System

Inspect the EVAP canister and associated hoses for damage.
If damaged:
1. Disconnect any hoses attached to the EVAP canister.
2. Remove the canister and replace it with a new one.
3. Reattach hoses ensuring a tight fit.

5. Verify Fuel Cap Integrity

Check for proper sealing of the fuel cap.
If defective:
1. Replace the fuel cap with an OEM replacement to ensure proper sealing.

6. Reconnect Battery and Perform System Check

After all repairs, reconnect the battery.
Clear any diagnostic trouble codes with the OBD-II scanner and perform a test drive.
