Ive notice that my idle is hanging untill i come to a complete stop.Ive got a 6 speed and when put it N the idle hangs around 1,200rpm then drops to 700-850rpm at a complete stop.Ive cleaned the t-body and ran some injeter cleaner thought and still hanging.
Thanks

 

Check the IAC valve, also make sure there is no binding in the throttle valves and linkage.

 

Also check the throttle positioning sensor.
