Bingo.
And don't try to take off right away, they seem to stumble hard if you dont wait 10 seconds or so.

Ok, well I didnt clean the throttle over the weekend, seems to be a normal thing with the Mustang. No use of taking stuff apart.

I have an 06 gt to. Mine does the same thing, if you let it run for a little while it will drop down to around 1000 then after warms up will idle around 700.

If you take off to early and not let it run for a few seconds then when you idle it will go back and forth between 500 and 700 a couple of times then stay at 700.

I live in houston and it will do the same thing in the middle of the summer, when its 90+ degrees.

But it does do it more when its cold.
