Question: Why is my C7 engine experiencing rough idling and increased black smoke?
Answer: This is often caused by a clogged or worn 322-2733 fuel injector. Over time, carbon deposits restrict the nozzle, preventing proper fuel atomization. Replacing with a new 3222733 unit restores the precise timing and pressure needed for efficient combustion, effectively eliminating smoke and restoring idle stability.
Question: My engine has a hard start when cold, is the fuel system the problem?
Answer: Yes, a leaking internal seal in the injector assembly can prevent the fuel rail from reaching starting pressure. By utilizing our OEM-standard replacements, you ensure the pressure remains constant within the C7 fuel system, allowing for rapid ignition even in extreme weather conditions.
OEM-standard tri-metal structure: Our injectors use advanced metallurgy to handle the high-pressure cycles of modern engines. Trusted by repair shops and equipment fleets globally for their reliability.
