I have about had it with my 2011 Chevy Cruze. It has been to the dealership many of times in the past 6 months or so. I have had the valve replacement done new spark plugs, they cleanes the fuel injection and my car is still running with a rough idle. In all of my life I've never had a car as a dealership as much as this one has been. I have no warranty and it feels like it's going to die on me every time I'm sitting at a stop sign or when I try to go in reverse. Any ideas?
