Default Odd Idle issue.

Kind of driving me nuts.. When I start the car and just leave it idle, or drive normal and come to a light it idles steady at about 700rpm.

However, if i drive it hard, or hold the rpm at about 2500 for 30 seconds, when I back off or come to a traffic light, the idle will sit at about 1500 and just stay there for a while. Any idea why its doing that?

Check the datastream for the IAC and temp sensor in the front of the water pump.
