91 Buick Le Sabre stalls out

My car sputters and stalls out whenever I stop. It also stalls when I am turning and not applying pressure to the accelerator. What do you think the problem could be? Do you think it could be a T.P.S sensor?

There may be an idle air control valve that is malfunctioning. If that is it, it will be easy to fix.

Thanks, I will check it out and let you know if an air control valve wass the issue.
