I have a 08 Cobalt LS and it has a rough idle at start up and it cuts out and shuts off. THIS ONLY HAPPENS AT WARM UP. It stops after I hit the gas pedal a few times. If I drive the car before it hits normal operation temp, it will be sluggish and I can put the pedal to the floor and it won't do anything. I'm pretty sure this is the same that is occuring during idle. But after it happens it's fine. I cleaned the throttle body of all carbon build up so it's not that. I'm thinking a sticking injector? Any help is greatly appreciated!
