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.
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.
