- Repair Exhaust Leaks.
- Check Electrical Wiring and Cables.
Can I drive my car if it says engine power reduced?
Can you drive safely with the Reduced Power Light on? It depends on the cause of the reduced power. Often, the problems are minor. In rare cases, though, reduced power can cause more serious problems like a seized engine, or even an electrical fire.
What would cause reduced engine power?

Can spark plugs cause reduced engine power?
This causes many problems, like increased exhaust emissions, reduced fuel economy, and reduced engine power. A single misfiring spark plug can cause enough raw fuel to be dumped into the exhaust, causing it to overheat and damage the catalytic converter.
What causes engine power reduced?
The reduced engine power light comes on when the vehicle’s computer detects a fault in any of the systems that allow the engine to run optimally, such as airflow sensors, throttle sensors and oxygen sensors.
