i was hoping thats what they fixed, i was saying that to myself as i read down the page.... the idle air control motor or the thermo boost valve was crapped, causing the motor to not be able to boost in enough air to keep idle after the rpms come down so fast, also it would idle rough like you said as a result of the same stuff.....

 

How should I go about cleaning the idle air system? It's time I fix this problem.
