 You may have a bad IAC ( idle air control) but try cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC.

ok Hammer Time. I did everything you said and it gave it some improvement but it didn't quite fix it. It doesn't do it everytime you stop, but it does it ever now and then, and i actually cleaned it twice. So do you think i need to go ahead and buy the IAC now?? also there wasn't a small home under the throttle plate, u pub my finger all through there, looked in it with a flash light and didn't see not one small hole.

The hole near the throttle plate leads to the IAC. Unless you get a healthy spray in there, none of it gets to the IAC. It may or may not help. If the IAC is bad and binding. it will still stall.
