Rough Idle

[AJRK]

Recently, the 2004 XLT V6 I drive has been idling very rough. Makes no difference if AC is on or off, and improves very slightly in Neutral or Park. I took the car to my dealership, who said that since it was showing no codes, they didn't know what was wrong with it. Has anyone else had this problem? If so, what was the cause?
Thanks in advance.

i know what you mean, it also improves if you have it in park or neutral and give it a little gas... it feels like it would just before its ready to cut off... my 02 and my moms 05 do the same.
