Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fuel injector cleaning kit, compressed air, safety goggles, gloves, cleaning solvent.
Disconnect the vehicle battery to ensure safety during the cleaning process.
Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.

2. Access Fuel Injectors

Remove the engine cover (if applicable) using a socket set.
Disconnect the electrical connectors from the fuel injectors.
Remove any intake manifold or components obstructing access to the fuel injectors (follow manufacturer instructions for specific component removal).
Carefully remove the fuel rail bolts and lift the fuel rail with the injectors attached.

3. Clean Fuel Injectors

Set up the fuel injector cleaning kit according to the manufacturer's instructions.
Connect the cleaning kit to the fuel rail or directly to the fuel injectors, depending on the kit design.
Fill the cleaning kit with appropriate cleaning solvent.
Activate the cleaning kit to allow the solvent to flow through the injectors. Follow the recommended cleaning cycle duration specified in the kit instructions.
After cleaning, use compressed air to blow out any remaining solvent from the injectors.

4. Reassemble Components

Reinstall the fuel injectors back into the fuel rail, ensuring proper alignment.
Secure the fuel rail back to the engine and tighten the bolts to the manufacturer's specified torque.
Reconnect electrical connectors to the fuel injectors.
Reinstall any components or intake manifold removed earlier.
Reconnect the battery and replace the fuel pump fuse.
