What You'll Learn
Fuel injector problems
Fuel injectors are fuel metering devices that spray atomized droplets of fuel into the engine's intake manifold or cylinders. They are electronic components and can wear out, suffer wiring issues, or clog over time. A faulty fuel injector can cause rough idling, loss of power, or misfiring. If a fuel injector fails or clogs, engine power is reduced, and the engine may stall immediately after starting, fail to start, hesitate under throttle, or vibrate roughly. The check engine light will turn on, and there may be an odour of raw gas or visible leaks.
When replacing fuel injectors, it is important to use high-quality, OEM parts. The injectors should be the same to ensure even power across the engine and a proper air-fuel mixture for all cylinders. The battery should be disconnected, and proper precautions should be taken against fire. It is not recommended to attempt fuel injector replacement at home as it can be a complicated process and there is a risk of fire.
To replace the fuel injectors, the engine components, intake manifold gasket, coolant, and oil may need to be removed. The fuel injector is then disconnected from the fuel rail and electrical connector and removed. The new injector is installed in its place. When servicing fuel injectors, it is recommended to service or replace all of the injectors at the same time to ensure they are balanced in terms of flow rates. On-car cleaning of fuel injectors is not as effective as off-the-car cleaning because the injectors have tiny internal filter baskets that should be replaced.
The average cost for a Saturn Vue Fuel Injector replacement is between $281 and $347 but can vary depending on the car. To prolong the life of the fuel injectors, it is recommended to follow the scheduled maintenance schedule for cleaning the fuel delivery system and injectors.
