Your check engine light is on and the code says it is running lean?

If your check engine light is on and the code indicates that your engine is running lean, it means there is too much air and not enough fuel in the combustion mixture. This could be caused by a variety of issues, such as a vacuum leak, faulty fuel injectors, a clogged fuel filter, or a malfunctioning mass airflow sensor. It's important to diagnose the root cause promptly, as running lean can lead to engine damage over time. Consider consulting a mechanic for a thorough inspection and potential repairs.
