Why is your Chevy Cobalt burning so much gas?

Your Chevy Cobalt may be burning excessive gas due to several factors, including a faulty oxygen sensor, which can cause the engine to run rich, or a clogged air filter that restricts airflow, affecting fuel efficiency. Additionally, issues with the fuel injectors, such as leaks or blockages, can lead to improper fuel delivery. Poor maintenance, such as low tire pressure or worn spark plugs, can also contribute to increased fuel consumption. Regular diagnostics and maintenance can help identify and resolve these issues.
