Stalling 98 windstar

This is my Grandmothers van and she claims it would stall out! I hadn't ever had it happen when I drove it, or when riding in it. But it just stalled on me 4 times at once does anyone know what is causing this to happen, i am open to suggestions, please help!

A very common cause of stalling is the IAC....Idle Air Control.
Most common failure is..when you let off the gas....it stalls.

Location....it is the metal cylinder that is on top of the big black upper intake manifold.....next to the Throttle body.

The IAC is held in place by 2 bolts.....and has 1 electrical connector.

People have cleaned it and managed to get more life out of it..... Is not real expensive and is very easy to replace yourself.

Since it is not your car..... I would recommend replacing it so that she will be less likely to have a problem when she is out and about without you and your toolbox along.

and this happens anytime? she was leaving this morning and she was shifting gears, and it stalled out.

It might be your fuel pump. This happened in our other car and thats what it was.

thanks guys!
