I've had the misfires occur before normal operating temp. I've only actually felt the misfiring in 5th or 6th gears, but the Ford Tech noticed the misfires occur on takeoff as well. I wouldnt feel shaking or anything, but he could see it on the diag computer. I did notice a lack of power compared to my friends Ecoboost once the shuddering/misfiring started occurring.

Since the issue became noticed by myself I have obviously paid closer attention...and have noticed it happen in many situations.
Most frequently it happens going up a hill. Also happens if you accelerate from say a 30 mph zone to a 55 mph zone using boost boost to accelerate vs. rpm, it will cut in and out the whole way. Simply hitting the + a couple times with the cruise set and it builds boost it will do it sometimes. On small hills where it normally wouldn't happen I can get it to do it by hitting the + on the cruise control a couple times so it builds boost.
Last week I experimented while I was going up hill when it started the misfire, I put the pedal to the boards. While it didn't fall on its face or throw any codes, it seemed like it had absolutely no get up and go.
Been holding off bringing it in cause its hunting season. Back seat is full of all my hunting gear and I go probably 5 times a week. Just a pain to deal with right now...may just hold off until January when hunting is done.

Plug Gap
I am almost at the 50000 k mark and my persitant complaining has earned me an extended 200000 drivetrain warranty. Truck shudders the same as always, but at least I have some peace of mind.
I will be changing my plugs this comming weekend as well as my transmission oil/filter. I will gap to 32.
My fuel economy is still great, 10.3 k per hundred averaged since day go.
Better than my Wife's Edge.
It has had every software upgrade available, shield over cooler, no change. Only thing I notice off line performance diminished with latest TSB.
That does not bother me though cause I am not a hard driver.
My cousin just purchased a 12 XLT 5.0. My shudder scared him away from the eco boost.
I will keep nagging Ford until they tell me to buy a Chevy.
Cheers.

Do yourself a favor and don't, under any circumstances, take delivery! Save yourself a lot of brain damage and shop for anything that will work better than these things.
A word to the wise, don't do it. You've been warned! I hope I don't see you on here in a couple of months wining about the same stuff we got taken on. Be smart!

Well I have been suspecting for some time now that I have this dreaded shudder as well on my beautiful 2012 FX4 with appearance pkg. Today while pulling out to pass towing an empty aluminum ski-doo trailer the truck started shaking violently and fell on its face. I am so disappointed.
I have been following this thread for over a year now and have read every page and thought how lucky I was to not have this issue.
Two thinks I will say:
1 My truck developed this over the last few thousand KM's
2 Its definitely not transmission related as when it happened I threw it in neutral and planted it to the floor but it would not rev past 3K RPM.
Anyway I hope this gets resolved. I purchased this truck to tow my TT but I dont feel it is capable of doing it now.

2012 5.0 9k miles yesterday
approx 1k miles:
ago tried de-gapping the plugs from .054 down to .035
misfire seems to have gotten slightly better but still most definitely there, but could also be from less load on engine now due to cooler temps/not using AC.
TODAY:
took truck in for oil change so figured I'd have them check it out. no misfire codes found. tech COULD feel shudder/surge/misfire whatever you want to call it. had the NEUTRAL MISFIRE PROFILE cleared as mentioned by the OP somewhere else in this thread and had comp reset. I drove at lunch and no change whatsoever. I also have a funky tire wear issue on the front that they said to drive it for another few thousand miles and see if it continues, bring it back and we will take a look-see.
so at this point I will continue to drive it and in a couple thousand miles I'll be bringing it back and having them re-evaluate the "misfire" issue.
considering how few people have gotten this problem resolved I dont think it will get me anywhere, but at least its documented in the warranty history wich was all I was really concerned with to begin with

There will be another TSB coming out very soon that addresses this particular issue. And most dealerships won't perform a TSB unless your vehicle has a documented problem.

Took my 5.0 Screw to the dealer last week with shudder complaint. Took the tech for a ride and he felt what I was talking about. He hooked up some type of vehicle recorder and told me when it happens, hit the button on the recorder. I took the truck back yesterday and they removed the recorder. After a download and call to Ford, I was told that there are several codes coming up. I was told there was a problem with the throttle body and the gasket. Once those are replaced, they have to drive it to "retrain" something. Anyway, it was all spanglish to me, but I will post up if it helped.

bryan8252 - I'm very interested in the outcome of your situation. I am experiencing the same issues as you with my 5.0. I originally thought I had the same issue the Eco guys but after following this thread for quite awhile now, I realize mine is not as severe as theirs. It's more like a misfire that is constant and causing the engine to shudder when it happens.
