Chevrolet Aveo 2007 Check engine 202000 miles
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.

Chevrolet Aveo 2010 5 hatchback, 1.6 120000 miles
Car is a 5 speed. When I start driving in 2nd and 3rd and 4th gear around 2000 rpm the car sputters just till like 3500. No engine codes. I noticed the vacuum jumps around d from being negative vacuum positive pressure. Is that causing my issue?

El coche al encender tiene pequeñas pulsaciones, cuando se da marcha, el coche tiende a perder potencia. Sin embargo cuando el auto llega a su temperatura, actúa de manera correcta.

The fuses and relays were also checked and the acceleration and jerking problem still persists. I need to check the pedal sensor. I imagine it may be dirty and that may be why it is jerking.

Sometimes my car turns off during driving,without any alarm.it switched on right after that. Nobody find out the problem. I need help
Check your wiring, especially grounds to the chassis and the connector on the ignition coil. Also, see if your main relay or crank/run relay gets hot after you shut the engine off. Aveos are known for wiring issues.
I had the same problem and fixed it by going through every connection, removing and reinstalling them properly. That included the ECU plugs, ignition coil connector, battery ground wire, and more. Sometimes it’s just a bad or loose connection causing all the trouble.

Chevrolet Aveo 2005 Manual 238000 miles
When I'm driving in 3rd or 4th gear and the speed is accelerating, the car bucks and jerks. And it does the same if in low gear and the rpms go under 2000. Mainly in 2nd gear. I know I have bad oxygen sensor and catalytic converter.

Thank you!
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.
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.
