1. Remove the intake manifold or throttle body if required for access.
2. Disconnect the electrical connectors from each fuel injector.
3. Remove any retaining clips or bolts securing the fuel rail to the manifold.

4. Clean Fuel Injectors

Sub-steps:
1. Use a fuel injector cleaning kit or pressurized canister with cleaning solvent.
2. Attach the cleaning kit to the fuel rail or directly to the injector ports.
3. Follow the instructions on the cleaning kit to cycle the cleaning solvent through each injector.
4. Allow the solvent to sit for the recommended time to dissolve deposits.

5. Reassemble Components

Sub-steps:
1. Reattach the fuel rail and secure it with retaining bolts.
2. Reconnect the electrical connectors to the fuel injectors.
3. If removed, reattach the intake manifold or throttle body.
