Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
To Remove
Scrupulous cleanliness must be observed when carrying out any work on the fuel rail and injectors. Thoroughly wash the area round the injectors, fuel rail and intake manifold and blow dry with compressed air.
- Remove the engine covers.
- Undo the hose clips on the rubber duct. Disconnect the IAC valve's hose and unplug the rear knock sensor's connector from the duct. Remove the rubber duct. Undo the intake manifold's retaining stay and cable conduits.
- Disconnect the throttle and Cruise Control cables from the throttle lever and bracket. Also disconnect the crankcase ventilation and brake servo vacuum hoses.
- Remove the seven nuts securing the upper half of the intake manifold.
- Raise the upper half of the intake manifold and support it by means of a rubber mallet or the like.
Plug the intake manifolds with paper or rags to prevent screws and the like from falling down into the cylinders.
WARNING: Since replacement of the injectors entails working on the car's fuel system, the following points should be observed in connection with installation:
Work only in a well-ventilated area. If approved equipment for the extraction of fuel vapor is available, be sure to use it.
Wear suitable gloves. Prolonged contact with fuel may give rise to skin irritation.
Keep a class BE fire extinguisher near at hand. Be mindful of the danger of sparks caused by short-circuits and when connecting and disconnecting leads, etc. in electrical circuits.
No smoking anywhere in the vicinity.
