I also had the same problem, But the problem lies in the switch the actual hold switch on my aveo there is a side entry way you can pop off the one on the left will give you access to the switch. what could of happen is theres is condensation in inside the switch. then when it gets cold it freezes causing the switch to malfunction. This could happen either by spilling something on the switch or using a cleaning solvent like armorall, YOU MUST BE CAREFULL WITH ANYTHING LIQUID NEAR THE HOLD SWITCH. Also the car going from warm when you drive then cold when you park it at night. My car was in warranty and remind you I came up with is the dealership had no idea what was wrong. they reseted the computer it worked for a week then was happening again. I have knoweldge in switches/wiring so i decided to check pot the switch and open it up and sure enough there was condensation took it to dealer told them to try a new switch works perfect and going on 5 months with out problems. Replacing the switch can solve pretty much every problem that is stated here i think. Also take a look at the wiring and connections for older aveos

check tps sensor (throttle position sensor in backside of the throttle cable) and map sensor (manifold absolute pressure on front little 1 inch sensor with vacuum line) make sure there plugged in. the ecm (engine control module driver side inner fender) and tcm (transmission control module under dash) both need the data to know when to upshift and increase fuel/air. Otherwise the computer runs default values and guesses off of other sensors giving poor performance. also disconnect battery for 15 min. usually resets aveo service lights if you dont have a scanner.

oh the side of your transmission, above the halfway point, there will be a plug that you can open. (don't open the plug on the bottom of the transmission as that's the drain plug). When you open the plug, some fluid should leak out meaning it's at the right level. If nothing leaks out, pour some fluid in until it starts to run out and then replace the plug.

I've become SO FAMILIAR with this problem on my own Chevy Optra. The first time it happened, I took it in to my dealer. It cost me over $100 and I SWORE it would never cost me that again. It really IS the fuel system. (Sticking with Shell's "detergent" gas doesn't help!) Simple solution is to add a bottle of fuel SYSTEM cleaner (not just the fuel injector) and the FIRST sign of trouble or with each oil change. No more problems !! "Live and learn and pass it on !"
