Fuel injectors allow fuel to spray directly into the engine of a vehicle without a carburetor, where the fuel then burns over a small amount of time. A dirty fuel injector in a Buick Century can lead to dirty exhaust emissions and can also affect the Buick’s overall performance. Cleaning a Buick Century’s fuel injector, a moderately easy task, does not require you to remove it from the car frame.
Tools Used: Tools, Cleaning solvent, Pressurized solvent, Rubber gloves
Clean a CFI Fuel Injector
Turn the Buick Century engine off, and open the hood to allow access to the fuel injectors.
Disconnect the fuel pump on the right side of the Buick engine, and replace it by hooking up a pressurized solvent. Removing the fuel pump will stop a flow of fuel from flowing through the Buick engine when you turn it on.
