My cobalt tries to stall when I stop or slow down. The Idle shows that it just drops to almost -0- upon stop or slow down and then shales the whole vehicle trying to staty running. Dealer says no problem when hooked up to a machine, please help.

Did you ever have success diagnosing or correcting this issue? I'm seeing a similar issue with mine. Used to only happen on cold days, starting to occur this spring, too. I have seen a CEL on mine -- sensor issue if I remember right.

I have the same problem as well. Only happens when its cold outside. Throttles to the point where the car is going to die and then bounces back up and will continue untill the accelerator is pressed. Did you find any solutions to this?
