GMC Terrain stalling at stops and engine ticking with knocking on the right side on GMC Terrain

Some GMC Terrain owners report experiencing stalling at stops, which may be linked to fuel system issues, air intake problems, or ignition system malfunctions. Additionally, some owners notice engine ticking and knocking on the right side, potentially indicating problems with the exhaust cam solenoid valve or a faulty lifter. The knocking and clicking noises could signal significant engine issues, prompting a check of the oil level and quality to ensure proper lubrication. Furthermore, a dirty air filter may restrict airflow, causing the engine to run lean and potentially stall. It is recommended that owners experiencing these issues consult a qualified mechanic for a thorough inspection to diagnose and address the problems promptly, as timely resolution can prevent further damage and ensure the vehicle's proper functioning.
