Sounds like your Idle Air Controller is sticking shut. You will not get a trouble code if the voltage is correct. It's located on the side of your throttle body. Sometimes you can clean it and it will work but that problem will come back so for $50 to $75 you can replace it yourself.

Happy Thanksgiving!!
