Product Overview
Hard starting, rough idle, uneven cylinder contribution, excessive smoke or a noticeable loss of power can point to injector trouble after compression, fuel supply and injection timing have been checked.
Replacing worn injectors restores the metered fuel delivery and spray pattern the engine depends on for clean combustion. A matched set is useful when several injectors have similar hours or testing shows more than one nozzle is out of specification.
