Why my car will not stay crank unless my feet os on the accelerator? on 2005 Ford Taurus

when I crank my car I have to keep my feet on the accelerator to keep it running.When I stop at a traffic light I have to keep my feet on the accelerator and the other feet on the brake.This also happens when I'm backing out of my driveway.

Need to have the engine diagnosed, you may have a very large vacuum leak, leaks or other things. Does the Service Engine Soon or Check Engine Light ever come on? If so need to get that code and address it ASAP!! here are some shops:
