1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool before starting.

2. Remove Engine Cover

Using a socket set, remove the bolts securing the engine cover.
Carefully lift off the engine cover and set it aside.

3. Access Fuel Injectors

Remove the intake manifold if necessary, following these sub-steps:
- Disconnect any electrical connectors and hoses attached to the manifold.
- Remove the bolts securing the manifold using a torque wrench, noting the sequence.
- Carefully lift the manifold off and set it aside.

4. Remove Fuel Injectors

Disconnect the fuel injector electrical connectors.
Remove the retaining clips or bolts holding the fuel rail in place.
Carefully pull the fuel rail with the injectors away from the engine.
Remove the fuel injectors from the fuel rail by gently pulling them out. Inspect O-rings for damage.

5. Install New Fuel Injectors

Lubricate new O-rings with engine oil before installation.
Insert new fuel injectors into the fuel rail, ensuring they seat properly.
Reattach the fuel rail to the engine, securing it with retaining clips or bolts.

6. Reassemble Engine Components

Reattach the intake manifold, ensuring all electrical connectors and hoses are secured.
Replace the engine cover and secure it with bolts.
Reconnect the battery.
