Problem overview

Some Chevrolet Camaro owners report experiencing issues when the check engine light activates with codes P0171 and P0914. The P0171 code indicates a lean fuel mixture in the engine's bank 1, which can lead to symptoms such as reduced power, rough idling, and hesitation during acceleration. Common causes for this code include vacuum leaks, faulty oxygen sensors, clogged fuel filters, and malfunctioning mass airflow sensors or fuel injectors. Additionally, while details regarding the P0914 code are less common, it is still important for owners to be aware of potential underlying issues. Owners experiencing these symptoms are advised to have their vehicle inspected by a qualified mechanic, as addressing these codes promptly can help prevent further damage and ensure optimal performance of the Chevrolet Camaro.
