Stumble when coming to idle/stop issue

Hey guys, I was wondering if any of you were having this issue:

When I'm coming to a stop sign/stop etc, sometimes my car stumbles by dropping way below idle then regaining itself and revving over 1300k then comes back to idle. As of recently, it's gone worse- it doesn't do that as often- it just stumbles then stalls out completely. Real cool looking at a stop light not knowing your car is off when you expect it to be ON!

I've tried 5 different gases here in Cincinnati thinking it was some stupid shit like that but it doesn't matter. It's the car. A buddy of mine with an ST (Shaun) has the same stumbling issue but not nearly as rough as my situation.

I have been trying to actually get it on video before taking it up to Ford hahaha because I know they won't know.

Anyone know of a possible TSB or have had these issues? Any help appreciated.

2013 ST3 bought last September by the way, problem didn't start at all til the last 2 months.

Check for any possible air leaks in the intake system (from air box to throttle body).
Make sure all clamps are tight.

TSB 13-9-7

This is the TSB for the issue I believe you are having. You can do the work yourself because Ford just loves to give a hard time about doing any TSB's.
