Solution

1. Preparation

Tools Required: Fuel pressure gauge, OBD-II scanner, multimeter, socket set, torque wrench, injector cleaning kit.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal.

2. Access Fuel Injectors

Remove the engine cover if equipped using a socket set.
Relieve fuel pressure by removing the fuel pump relay and starting the engine until it stalls.
Disconnect the fuel lines from the fuel rail using appropriate tools.

3. Remove Fuel Injectors

Unplug the electrical connectors from each fuel injector.
Remove the retaining clips or bolts securing the injectors to the fuel rail.
Carefully pull the fuel injectors out of the fuel rail, avoiding damage to the O-rings.

4. Clean or Replace Injectors

If cleaning: Use an injector cleaning kit according to the manufacturer's instructions to remove deposits.
If replacing: Install new fuel injectors, ensuring to lubricate O-rings with clean engine oil before installation.

5. Reassemble Components

Re-install the fuel injectors into the fuel rail, securing them with retaining clips or bolts.
Reconnect the electrical connectors to each injector.
Reattach the fuel lines and ensure they are tight.
Reinstall the engine cover if removed.

6. Final Checks

Reconnect the negative battery terminal.
Restore fuel pump operation by reinserting the fuel pump relay.
Start the engine and check for leaks around the fuel injectors.
