Take off your air intake hose to the throttle body. Spray carb cleaner into the Idle Air Control Valve. See if that makes a difference. Here's a short video. Different car, but same idea. http://www.youtube.com/watch?v=i82s4ZfR2js

Here's a short video on how to test your Throttle Position Sensor. http://www.youtube.com/watch?v=1KEd52QJMNc Here's the test for the IAC valve. http://www.youtube.com/watch?v=j9tUcS7Y3Qw The IAC valve test only will tell you that it has power to it. Won't tell you if it's plugged.
