Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle's battery to prevent electrical shorts.
Allow the engine to cool completely.

2. Remove Components

Tools Required: Socket set, ratchet, extension.
Remove the engine cover (if applicable) by unscrewing the fasteners.
Disconnect the air intake duct from the throttle body.
Remove the intake manifold (if fuel injectors are located beneath it) by unscrewing the bolts and disconnecting any attached hoses and sensors.

3. Inspect and Clean

Carefully remove the fuel injectors from the fuel rail by unclipping the retaining clips and pulling them straight out.
Inspect each injector for clogs or damage. Clean the injectors using an ultrasonic cleaner or fuel injector cleaning solution if needed.
Replace any damaged O-rings on the injectors.

4. Reinstallation

Apply a small amount of engine oil to the new O-rings to facilitate installation.
Reinstall the fuel injectors into the fuel rail and secure them with the retaining clips.
Reinstall the intake manifold and ensure all bolts are torqued to the manufacturer's specifications (typically around 16-22 lb-ft).
Reconnect the air intake duct and engine cover.

5. Final Checks

Reconnect the battery and turn the ignition to the "ON" position for a few seconds to prime the fuel system.
Start the engine and check for leaks around the fuel injectors.
Allow the engine to reach operating temperature, and perform a final inspection for smooth operation.
