The injector delivers precisely metered fuel into the combustion chamber under high pressure, controlled by the engine's electronic control module. As a core, this is the recoverable unit returned to a supplier for remanufacturing, typically required when purchasing a replacement injector to offset the core deposit. A failing injector can cause rough running, power loss, or increased emissions.
