I bought my Cobalt in June 05, at first it was the best little car. Fully loaded, heated leather seats, sunroof, pioneer system with stock sub. 2 Months into the car I had to take it in for a leak in my "anti-lock brake valve". I've also had the chrome door handles replaced after i cut my hand and it did it again, the plastic piece around my sunroof fell off and has been fixed at a dealership 3 times .. that is still not attached. In 2007 I got into a car accident and had a new hood put on it (Which came from a dealership no longer open) which is now rusted the size of a half dollar! GM will not replace it because it has not rusted all the way threw. Really? Sell me a junk hood and say oops? For the past 3 winters everytime i stop when it is cold and i have my heat and heated seats on my rpm's drop and my engine power reduces, my engine and traction control lights both come on. I paid a dealership $75 to try and find the problem, which it didn't and took it back a year later for them to tell me nothing is wrong.
On a good note, great gas miliage and i love how it handles. I just hope my next GM vehicle doesn't have so many cosmetic issues and better service. Oh, My power locks do not work anymore and my chevy symbol fell off of my trunk. I feel like i drive a 5 year old beater.

I had the same exact thing happen to me, and I paid to get the whole throttle body put in, however a week later my car is doing the same thing. I have no idea what to do now.

Thanks sharkman. GM has contacted me and we are trying a different dealer. Maybe that will help. Taking it in Friday wish me luck!

Because of cost to pursue other avenues, I would first do this:
- confirm you haven't bought contaminated gas (water, seaweed etc - this has happened to me when I bought diesel in Sarasota FL once many years ago)
- then have the fuel filter replaced. _ hopefully it is a stand alone object in the fuel line, but there is a possibility it is part of the fuel pump assembly IN the tank, so in that case would not be cheap.
But I would have the tank checked for contamination and that should not cost too much unless it was found to BE contaminated. To check, go to local corner gas stn and ask them for a dab of litmus test paste. It is a light green. They put it on dip sticks when they guage the inground tanks when ordering gas. They wipe it on and draw it up the bottom 18" or so of the stick. At the point it turns to red from green, is the water level in the tank.
But...some stns have gone very hi tech and possibly that whole operation is automated now, so check around.
You might have to Google where u can buy the litmus paste and then have your mechanic dip your fuel tank.
While the Cobalts seem to have this throttle body issue, what you described happened to simulate fuel starvation also (by a clogged filter) especially how quickly the problem returned. Good luck.

Very good suggestions. We were just discussing a similar issue in a Toyota Corolla discussion here.
wrichards, if you live in a cold climate, and if the car spends long periods outdoors, you might try putting a bottle of Heet in the gas tank. It's about $3 and available at auto parts or discount stores like Wal-Mart. Sometimes moisture gets in there, whether already in the gas station's tanks, or in yours. If that's the case, Heet will work wonders. (if it works, I'd also consider going to a different gas station in the future.)
If it doesn't work, at least you'll have ruled that out as a cause for almost no money.

Good point also, Kirstie. I had forgot about the moisture in gas due to condensation in cold winter climates (try to keep tank full to reduce that, wrichards) and the potential freezing of moisture in the filters.
I suspect that the Heet you mentioned is just a methyl hydrate of some sort. Hopefully/probably rubber seal friendly, which can't be assumed with hardware store bought MH. I suppose that is ONE good thing about ethanol use in gas in recent years. It has a natural type of moisture evaporation quality in gas.

The methanol (wood alcohol, methyl hydrate) that's in Heet or any other brand of product that "removes water" from gasoline is a good check. But I don't personally recommend its frequent use because of seals in the system.
If the poster uses gasoline that contains ethanol, it probably keeps any condensate picked up from their tank bottom and burned. The ethanol gasolines have additives that help the gasoline and ethanol stay mixed and suspend the water present.

Gotcha. We don't have ethanol-blended gas in this part of the state, which may contribute to our issues. We've had to use Heet twice in the past 1.5 years, which isn't bad. If the seals go... well, it is a 13-yr-old truck that was cheap. You can only expect so much.

That ability to carry away condensed moisture is the only advantage of ethanol, in my opinion. I believe it's mandated at a certain level of total usage in Ohio, so most stations have ethanol blended.
I didn't know there were areas that were alcohol free!
