A cylinder 3 misfire in a 2004 GMC Envoy indicates that the engine is not firing properly in that specific cylinder, which can lead to rough idling, decreased power, and increased emissions. Common causes include faulty spark plugs, ignition coils, fuel injectors, or compression issues in the cylinder. Diagnosing the underlying problem often requires checking the ignition and fuel systems, as well as performing a compression test. Addressing a misfire promptly is important to maintain engine performance and prevent further damage.
