“While driving, the car loses throttle and the engine does not function at all. The following error shows on the dash: inoperative see operator's manual . When this happens, your only choice is to coast to a safe place. After restarting the car, it will function for a short time, only to reoccur. This obviously can be deadly if you cannot get off the highway before the car comes to a stop. This has happened at various speeds.”
