Faulty Throttle Body

A faulty throttle body is one of the most common causes of engine reduced power on Chevy Malibus. The throttle body is responsible for controlling the airflow into the engine, and if it is malfunctioning, it can limit the engine’s performance.

Dirty Air Filter

A dirty air filter can restrict the airflow into the engine, causing it to run inefficiently. This can trigger the engine reduced power safety feature and limit the car’s performance.
