To remove the fuel injectors, start by relieving the fuel pressure and detaching the battery cable. Remove the PCV hose and, on V6 models with performance suspension, the suspension brace. For V6 models, remove the assembly retaining the Vacuum Switching Valve (VSV) control solenoids and the air intake plenum to access the rear fuel rail. Disconnect the fuel injector electrical connectors and the fuel lines from the fuel rail. Remove the fuel rail mounting bolts and carefully lift out the fuel rail with the injectors attached. Twist and pull the injectors to remove them from the fuel rail and store them in a labeled container. If reusing the injectors, replace the grommets and O-rings. To install the fuel injectors, reverse the removal process and tighten the fuel rail mounting bolts.
