Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, multimeter, socket set, torque wrench, safety glasses, gloves.
Disconnect the negative battery terminal to prevent electrical shock.
Relieve fuel pressure by removing the fuel pump fuse and starting the engine until it stalls.

2. Remove Fuel Injectors

Sub-steps:
1. Remove the engine cover (if applicable) using a socket set.
2. Disconnect the electrical connectors from each fuel injector.
3. Detach the fuel rail by removing the bolts securing it, using a torque wrench for proper reassembly.
4. Carefully lift the fuel rail off the injectors, ensuring not to damage any components.
5. Remove the fuel injectors from the fuel rail by pulling them straight out.

3. Inspect and Clean

Sub-steps:
1. Inspect the fuel injectors for any clogs or damage; replace any that are faulty.
2. Clean the injector ports in the fuel rail with a cleaning solvent to remove any carbon buildup.
3. Use a soft brush and cleaner to gently clean the exterior of the injectors.
4. Check the O-rings on the injectors; replace if they are worn or damaged.

4. Install New or Repaired Fuel Injectors

Sub-steps:
1. Lubricate the new O-rings with clean engine oil to ensure a proper seal during installation.
2. Insert the new or cleaned injectors back into the fuel rail, ensuring they seat properly.
3. Reattach the fuel rail to the engine, securing it with the previously removed bolts using a torque wrench to the manufacturer's specifications.
4. Reconnect the electrical connectors to each injector.

5. Reassemble and Test

Sub-steps:
1. Reinstall the engine cover (if applicable).
2. Reinsert the fuel pump fuse and reconnect the negative battery terminal.
3. Start the engine and check for leaks around the injectors and fuel rail.
4. Allow the engine to reach normal operating temperature while monitoring performance.
