While going up a hill I had the cruise on and lost power. The reduced engine light came on and the cruise has quit. I pulled over and turned off the motor and restarted and the the was out but the cruise still didnt work and then the light came back on after a couple of miles. It comes on everyday and most times if I run the air conditioner it sputters. I have learned to deal with the service engine light but I dont know what to do about the reduced engine power and the cruise.
