I just ran out to start my car because its about 15°. My door was locked so i had to run back to get my key from the car. When i went to shut it off i pulled the key out and the car was sputtering still. It was like it stalled out it did not sound healthy at all. Normally when you turn the key to off it shuts right off, but it did not even come close to doing this, it was still running then sputtered dead. Its never done that before and its kinda worrying me. Could it be because it was still cold when i shut it off? Or should i take it in the the dealer tomorrow. Ill try it when i get home and see how it is when i shut it off when its warm. But i just figured id ask you guys if its happen to anyone else. Thanks

 

Check your fuses.

 

probably still in cold start, runs very rich when cold.

 

there is nothing wrong with you car....

 

X2....this is funny...the carburated engines in the past used to be notorious for this. Its just unburned air/fuel mixture in the engine. I think they used to call this "run-on" if I'm not mistaken.

all good guesses. but not. the cobalts sometimes have that problem. its an issue with the pcm/bcm/switch. wont turn off right away. also will continue cranking when you try to start it and it doesnt fire but you have released the key...just saying

 

that would b bad

 

Mine does that... I love it. I just slap the key to START real quick and it keeps cranking till it starts. When my friends are in the car and they see it do that... they are like, "Z0MG! UR car iz a 1337 H4X0r!"

 

mine used to do that and I loved it, now it doesn't

however it also would turn off right away... so i dunno

 

Srsly, my BCM is going in the goddamn river. Perhaps still attached to the car if it doesn't play nice.

Cool thanks. I was just curious if that was a common problem with cobalts. Thanks everyone. Its good now and i freak out for no reason. Im new to these cars i drove a Tiburon for 2 years so im just getting to know GM.

 

yea this is what it sounds like hot spots in the motor still burning left over fuel. Does the car sound like it has huge knock and shakes feels like it's going to jump out of the car. it scared the **** out of me the first time I saw this.

 

so its not supposed to do that?

 

This is more an Ion problem these days for some reason...........

Thats normal dick. Its intelligent cranking, thats not what Qwik was talking about

 

Haha... okay. That's what I thought. It is nice though...

I have boogers in my nose.

 

sorry sir, but most new model gms will start for you, or will crank until it will fire..its a luxury, not a problem. and dont worry, your car is fine...everyones car will do the same exact thing in cold weather.... unless you actually let it warm up..

 

i have no idea what you are talking of, of couse GM cars start off that way its not a luxury, its by signal from the computer not the key itself, but Some Cobalts have a glitch and can start, and you can "turn off" remove the key and the car stays running.

 

When it's really cold out and I just start my car and move it forward in the driveway my car used to do this. It doesn't anymore...because I don't drive it.
