It is reducing engine power because a sensor dictated a serious problem and to keep the engine from damaging itself it'll go to engine power reduced stage and it vibrates because its at a rough idle
Reduced engine power, on your 2005 Pontiac Montana, can because by several things. The most common cause of reduced power is a lack of fuel.
The reduced engine power light means that there is a problem with the battery or power system. It almost always means a battery connection issue.

The engine power reduced light will turn on in Chevrolet HHR when a failure is detected in one of the sensors or engine components. An OBD II code reader can determine the cause and help with making repairs.

I have a 2006 Saturn ion. The reduced engine power light came on and the car still runs but will not accelerate and only goes 30mph
In order to use less gas, the size of the engine is reduced, but it also reduces its power. A turbocharger is then added to increase the power of the engine.
have battery tested bet it is no good
Could be one or more of many possibilities. It would have to be diagnosed.
When my Reduced Engine Power Light came on in my 2004 Envoy it ended up being the entire pedal assembly and the electronics that control it. If I remember correctly it ended up setting me back around $500.00. Hope this helps!!
