Car jerks then shuts off especially when coming to a stop or after changing gears. It also jerks when on an inclined street, the car starts to roll back, jerks after acceleration, then cuts off completely. After it shuts off, it takes a while for it to turn back on and only to find the check engine and epc light on. It's come to the point where I'm too afraid to drive my own vehicle.
