If you can not hear vacuum leak at it with brake on or off.
And it does not change idle with it pulled and plugged it should be good.

Well i changed the IAC valve and then drove it on the highway for 17 miles then had to slow down for an off ramp and it stalled again. It would not start for about 20 mins. Just turns over but no fire. Usually it will atleast try to fire. I then pulled off the vacume line off the master cylinder and pluged the hole and no change, reatached it and waited about 5 more mins and tried to start again and it fired and drove 1 foot till it died again and so i just left it there and will drive it home tomorrow when its a cold engine again.
