This is typical when the throttle bore needs to be serviced, here is a guide to help with instruction below for your car.

Also, I have seen a bad engine coolant temperature sensor cause the same problem so I would unplug it to see if the problem changes, Check out the images (below). Please upload pictures or videos in your response to any problems so we can see what to help you with.
