Fuel Injectors

Fuel injectors are nozzles that deliver a high-pressure spray of fuel that mixes with air on the intake stroke of your engine's pistons. A failed injector can cause a regular misfire, rough idle, poor fuel economy, roughness or loss of power (and will register a trouble code that will illuminate the Check Engine light). If you have pinned down a drivability problem to a failed injector, check out our selection of injectors from brands like ACDelco®,Bosch, Carquest®, Delphi, and Motorcraft®.
Years ago, carburetors were superseded by fuel injection, which uses a tiny nozzle in each cylinder to deliver a precisely metered spray of fuel to mix with air on the pistons' intake stroke. While fuel injection is a lot more reliable overall, injectors have been known to clog or fail. This will usually manifest itself as a regular misfire, especially under load, and will also register a trouble code and illuminated Check Engine light.
If you suspect you've got a failed injector (and see a trouble code to that effect), it might be best to replace all the injectors at that time. Shop Advance Auto Parts for the best OEM-quality fuel injectors for your vehicle.
