The reduced engine power light comes on to make you get your problem fixed ASAP!
It may be a rich code being picked up by an O2 sensor but whatever it is, the code must be diagnosed and cleared. You may disconnect your battery for 15 minutes to clear the code to see if it resets but if you are not mechanically inclined then you should go to a reputable GM dealership to get it fixed.

Light went off and has stayed off. Now my "service engine" light keeps coming on - I'm concerned that I may have a crack in the gas tank as I have read many many other Envoy owners have experienced.
