I have no sensor coming on in my car and it is just stop

If a car runs ok except it will not idle....the problem is usually a vacuum leak. With a vacuum leak you get the air/fuel ration off to the point the car is way lean. Look for vacuum leaks or lines that are completely unplugged. there is usually a plastic fitting somewhere on the intake and vacuum lines run to the cruise and heater controls.
