Having a little miss on 2003 Lincoln Navigator

My car is not idling very smooth. Other than that it is great. What can cause this?

this is not a awnser to the question but i have a 03 navigator that slightly shakes and a complete stop! do you have this problem also?
Your engine could have a vacuum leak, dirty injectors, old spark plugs to name a few things. Low idle speed can cause this too.
Do you have a check engine light on or any other warning lights?
