Had a problem with the air channel the plastic part after the air filter. Found had a cut that wasn't visible unless I took it apart.
I replaced that part and the car got better.
The initial symptoms basically was the check engine lights up and doesn't blink, the car's rpm goes up and down on it's own, some times it stalls.
After changing the part, it happens WAAAY LESS. I had someone test the voltage around the engine body and the output varies from place to place. The check engine lights after some time of the AC being on.
My car had almost the same behavior. On a cold start, it would stall, or the RPM would drop so low it felt like it was about to shut off, then suddenly climb again. If I let it sit for around 10 minutes without driving, the problem would disappear, and the idle would stabilize. Did yours do that, too?
Apparently I had a cut in the air hose, a dirty map sensor.
Fixing those fixed the problem with the check engine light and the high rpm, but not the stalling after a cold start. Turning the car off for a minute seems to help with the stalling now.
However I think due to the cut in the air hose has lasted over a month, the might be a clog in the injectors.
Apparently, the vacuum leak wasn't the only issue. It seems that this is a common issue with Aveo and I found the reason after almost a year.
It seems tht the hoses connected to the EVAP were not connect the right way. The car was collecting oil vapor and gas vapor and directing them to the wrong chambers.
Problem solved instantly after correcting them. Car is now amazing.
