    this may be int he wrong section if it is someone move it for me but i was wondering on my 08 silverado how can i tell when it cuts down to 4 cylinders??? no lights come on in the dash and my truck is just an lt1 so i dont have center that i can see verything like tire pressures and miles to empty. the only thing i can maybe relate is if i watch the rpms when i set my cruise itll lock in to od in cruise and then the rpms climb just a little bit more after that.
