same problem with my friend's aveo, only happens after cold start-up. it was the idle control valve i believe ( it was 3 years ago). Also, I don't know if you a have problems with the brakes? My friend's aveo's brakes wouldn't work sometimes and GM said there is no problem with it. A local shop found a leak in the break booster and a failed master cylinder at 6,000 miles! There was also a horrid noise that it made on the highway...after about a year, he got a lawyer and sued gm and won.
Disconnect the memory of the car and connect it Esaly the problem solved realy but you must give the car to Mécanique known this kind of problems ..ok maistro good luck
When the engine is cold, most cars will idle at an increased RPM to warm the catalytic converter. There is usually a fast idle control valve that uses a pellet of thermowax to keep the throttle pulled open when cold. As the engine heats up, the wax melts and releases control of the throttle. The jerking sensation is not normal, but the RPM when cold seems normal to me.
I have a 2009 Aveo , and this same problem happened to my car 4 months after purchased, the dealer changed the IAC valve and the problem disappeared. One week ago the problem returned. I also had a problem with the battery two days after the problem appeared. When I changed the battery for another one and turned on the car, the acceleration disappeared. I think the computer reset or something like that. Try this. Disconnect the battery for 5 minutes and check if the problem is gone.
send this car to the TRASH now!

It's under warranty, take it back! My guess is a bad Idle Air Control! Where do you think I work?

They're supposed to idle high when they're cold you idiot. Engine operating temp = 180F.
