Chevrolet Equinox rough idle with noticeable engine ticking noise on Chevrolet Equinox

Some Chevrolet Equinox owners report experiencing a rough idle accompanied by a noticeable engine ticking noise, which may be attributed to low oil levels or pressure, ignition system issues, or exhaust leaks. Additionally, engine rattle problems can arise from timing chain and tensioner complications. Owners have also noted that a rough idle could be linked to vacuum leaks, a dirty throttle body that restricts airflow, or a malfunctioning Idle Air Control Valve (IAC). After highway trips, some drivers report intermittent shaking while idling, particularly when stopped in drive at a red light, which may indicate underlying engine component issues. It is recommended that affected owners seek inspection from a qualified mechanic to accurately diagnose and resolve these concerns for optimal vehicle performance.
