Cadillac CTS stalling issue when cold, car restarts after stalling on Cadillac CTS

Some Cadillac CTS owners report experiencing stalling issues in cold weather, which may be attributed to several underlying causes. These include fuel-related problems that can be exacerbated by low temperatures, necessitating a thorough check of the fuel system. Additionally, a dirty throttle body is reported to cause stalling or low engine idle speeds, particularly in cold conditions, suggesting that cleaning it may alleviate the problem. Some owners have also encountered ignition system faults that contribute to stalling, highlighting the importance of inspecting ignition components. Furthermore, stalling accompanied by battery and oil lights can indicate potential battery or electrical issues, making it crucial to ensure the battery is in good condition.

A comprehensive inspection focusing on these areas is recommended for effective resolution of the stalling issue.
