Default Rough idle when warm?

If i start my car up after it has been sitting for a while and is cold it will fire right up. If i drive for a while and the car warms when i go to restart it after running into a store or something it idles real rough and if i don't give it gas it will stall out on me. Opinions? I am not real worried about his right now because i am going to be taking it off the road for the winter today.

injectors might be going out if youre having hard start problems after warm-up, hook up a pressure gauge and see if you hold pressure after you turn it off

Otherwise check for vacuum leaks, check your plug wires (my problem).

vacuum leaks could cause this? That could be interesting to see if that is the problem. Someone suggested that i could be having a vacuum because of my brakes, they act almos tlike i don't have pwer brakes, the heel of my foot usually comes off the ground when i have to stop the vehicle, with ASR disabled i can land the brakes to the floor and the tires don't even come close to screeching. I wonder if i could have a vacuum leak that would be affecting both of these problems. I don't think it is plug and wires, they have been done fairly recently.
