Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and vehicle is parked on a level surface.
Disconnect the negative battery terminal for safety.

2. Remove Engine Cover

Sub-steps:
- Use a socket set to remove any bolts securing the engine cover.
- Carefully lift off the engine cover and set it aside.

3. Access Fuel Injectors

Sub-steps:
- Disconnect the fuel line from the fuel rail using a fuel line disconnect tool.
- Remove the electrical connectors from each fuel injector by pressing down on the tab and pulling them off.
- Unbolt and remove the fuel rail from the intake manifold, ensuring to catch any fuel that may spill.

4. Clean Fuel Injectors

Sub-steps:
- Use a fuel injector cleaning kit with a pressurized canister of cleaning solvent.
- Attach the cleaning kit to the fuel rail according to the manufacturer's instructions.
- Start the engine and allow the cleaner to flow through the injectors, following the specified duration on the cleaner's instructions.
- Turn off the engine and remove the cleaning kit.

5. Reassemble Components

Sub-steps:
- Reinstall the fuel rail and torque the bolts to manufacturer specifications (typically around 16-22 ft-lbs).
- Reconnect the electrical connectors to each fuel injector.
- Reattach the fuel line securely.
- Replace the engine cover and secure it with bolts.

6. Final Checks

Sub-steps:
- Reconnect the negative battery terminal.
- Start the engine and check for leaks around the fuel rail and injectors.
- Allow the engine to idle and observe for any irregularities.
