Vehicle was shuddering or hiccuping accelerating and decelerating on its own without any warning lights turning on. Warning light (MIL) only came on after total failure and car would not move forward at all.without any control of acceleration I was forced to let the vehicle roll down the hill I was on to coast it into a parking lot to be off the road, while traffic was behind me causing a potentially dangerous situation as it was on a short street so line of cars driving the wrong direction with traffic entering behind going the appropriate direction.
