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!!
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.
