I was driving my 07 Chevrolet Hhr @ 45 mph when the dash display blinked then displayed engine power reduced, followed by a substantial reduction of speed.

The check engine light came on and stayed on. I drove 15 miles back home @ a speed of 30 mph. The vehicle refuses to accelerate beyond 30 mph.
