My car is 1.5L Nissian Latio CVT 4 year old. Last nite, at traffic light, I stop the car with the engine running... then when I want to move - I step on the accelerator with RPM going to 2300 the car hardly moved .. then slowly it begins to move, and picks up speed - when it moves it becomes normal again. However, it starts again when I stop the car at a junction.
It feels like starting the car on a 2nd gear - but mine is an auto car CVT...
