My car keeps shutting off every time I come to a stop or when idling and sometimes when I'm slowing the car to turn a corner. I hate it! Its really scary! Now I have to take it to a shop because I know nothing about cars and with all the different opinions I've been getting from everyone, I just don't know what the heck to think. Big bummer that's 4 sure.

My cobalt runs great until you stop are slow down to almost a stop. It start trembling and pulsating sometimes it shut off. I changed the gas cap it did't solve the problem
Car idle varies sometimes shuts off. Ignition switch is in run position.

Basically the rpm fluctuates when I get into semi heavy traffic, idling is a problem as well as simply slowing down. The rpm will suddenly drop Uber 1500 and although I'm pressing the gas peddle I get nothing until it jumps to 4500 rpms and will bob up and down like that. When this happens I get a clicking noise under my shifter handle as I depress the brake pedal. A seemingly erratic issue that sometimes accompanies this problem is that when I use my blinker, the dash alarm will ding until I turn it off. I've replaced everything(based on both dealer and third party mechanics recommendations) from throttle body, spark plugs, fuel filters, o2 sensor, fuel pump, had my tank dumped and flushed out, battery, as well as replacing the recalls that applied to my vehicle. The problem goes away after something is fixed but only anywhere from 2 days to 3 weeks. Making it difficult to pinpoint the problem. Please help!

At a idol it starts at 1000 then bounces back down to around 500-400, it does that four a few seconds then dies. Also at a complete stop or when I start to come to a complete start it dies.

Car stalls when the clutch is engaged while stopping when it cold outside has been happening for over two years. In December 2013 had the whole pedal with sensor and throttle body with sensor replaced. This fixed the problem until November 2014. The stalling started again and it's also gone into reduced engine power mode.
My car trembles what backing up, slowing down, and stopping. It hasn't shut all the way down on me yet but I have a feeling it may. it scares me all the time. Can a girl get a recall on whatever is causing this problem. I know im not the only one.
The speedometer fluctuates erratically when driving or idling. One time while idling, the speedometer went to 110 miles per hour and then back to 30 then it stalled out, the car was not moving. When on the highway the speedometer acts erratically and the car keeps jerking. I don't feel it is safe to drive. I have taken it to the dealer but they replaced the ignition for the second time and the car is still doing the same thing. They say they don't know what is really wrong with it, but I have read other reviews that states similar problems. I just paid my last payment on it today after five long years I bought this car brand new and I have tried to take good care of it. I am not happy right now.
