hi im having a problem with my nova, it was driving fine up until this afternoon then all of a sudden I pull away from traffic lights and it tryed stalling on me as I pulled away in first, I then change to second and as soon as I apply any sort of power it jolts quite harshly before giving me any power, it only happens when I first use the accelartor after changing gear in any gear, I seem to have lost a small amount of power too? any ideas?? it seems to be fine driving down the road its just the initial use of the accelerator after changing gear.
