Hi everyone, I just bought my car aveo 5 LS hacknack. make in 2006. auto.

I haveb been driving for two weeks n recently I have this problem when my car is not moving n my gear is either at D or R.

the car will jerk n idling went down n up. The feeling like misfire. went to the car shop. they change spark coil n tranimission sensor with new start spark also change.

after driving for a week, the problem is back. anyone have any idea what is the issues.

thank you
