2006 Mustang GT engine 'stumbles' when accelerating after a stop

My '06 GT has an intermittent problem, but one which has occurred enough to bother me. Several times now it has apparently misfired when accelerating after a stop. For instance, after exiting the highway and coming to the end of the off ramp, I try to accelerate and the car bucks, as though it's not firing, before accelerating normally. Prior to accelerating, the idle is perfectly normal. It doesn't die, but seems close. No warning lights or other clues appear. It's annoying, to say the least.
My guess is that it's an ignition issue. Anybody have a similar problem?

If it does it after a long drive I'd also say it's the fuel pump TSB.

My car is in the shop, right now, for this problem. Well, that and the groaning clutch pack, in the differential. Sounds like I have a seal, in heat, in my trunk, every time I make a turn. "ORK, ORK, ORK". I think that's seal for "Hey baby!"

My advice, print out the TSB and bring it in with you. Most service writers have no idea what you are talking about so... Now is an excellent time to buy the upper and lower control arms. You can install the lowers but as long as the tech is removing the gas tank anyway, have him put in the UCA!

It's down near the bottom "06-09-09 Hesitation on Acceleration"

And 2k5GTC vbmenu_register("postmenu_701591", true); you are right. That dude's avatar is nighmare material [shiver].

LMAO...I have the "horny seal" issue also...although it's more like "uruk, uruk, uruk." But then again, I'm not fluent in seal-ese. But the rear end noise doesn't really bother me, though, since I'm afraid that to fix the issue will invite more problems. I have a healthy distrust of anyone else working on my baby, but I'm not about to spend my $$ on what should be warranty repairs. Is the fix for the rear end moan likely to cause collateral damage? And will ignoring it lead to more problems? My '97 F150 (W/ 3.73 lim slip) had an overly tight clutch pack new and I chose to leave it alone. It crabbed initially on every low speed turn. It worked itself out over time. Now, 100,000 miles later, it's been virtually repair free--just a Pittman arm replacement and one power window motor.

Mine did the same thing last year. Ford replaced the fuel pump and no more problem. That's good advise to print the TSB and take it in.That's what I did because the service advisor at Ford had no clue.

The fuel pump access is under the rear seat. No need to drop the gas tank.

That's the same word, only the Southern dialect.

I got it fixed, near the end of my warranty because I wanted to get the most use out of the new clutch pack. I heard the new fuel pump fix works great.

I believe I have had that problem too. Initially I noticed it after I'd back out of the garage and head down the street. But it's always so slight I wondered if I imagined it (one day my husband was w/me and he noticed it too). I've also had it happen after a long trip at the stop sign at the end of the off ramp as you described. Again I wondered if I imagined it (apparently not!) Like your experience, it is very brief and I don't get any codes or lights (but mine comes no where near dying). FWIW, mine is an automatic. Please let me know if you learn anything about this.

The TSB regarding the fuel pump appears to be exactly the problem. (TSB # 06-9-9). The advice to print it out and take it in was good. My service "advisor" was clueless -- said he'd never heard of the issue. In fact, although I was polite, he almost acted a little irritated that I would dare to know more about it than he did. What happens is that air builds up around the fuel pump, especially after a long cruise. When you accelerate again, it gets sucked into the fuel line and the engine hesitates. In my case, badly. First time it happened, It was quite unnerving. I suppose that if you are accelerating very gently, (as in out of your drive) the relative lack of fuel won't be as noticeable.

Glad you're getting it figured out. Last October mine did the same thing and I printed and brought the TSB to the dealer. They were awesome and fixed it the next day under warranty.

BTW - how dare you know more about your car than the Ford Tech!

Thanks! I did print that TSB and saved it on my computer for future reference. I don't get any static (or disrespect) from the service dept. where I go, but I HATE taking my car in for anything b/c I swear they can't accomplish anything in under 2 days! I do NOT like to be w/out my car that long! But I will have this issue addressed before I'm out of warranty (I have 12,7XX miles now). Do TSBs expire?
And can I just say, firstly, I LOVE my car to death and can't imagine ever trading it away.....but, dang, I've never had a vehicle have to go back to the dealership as much as this one. In the first six months I had that clutches in the differential problem fixed--then the fuel tank issue was addressed. Perhaps I'm expecting too much for my $29,000! My husband's 2005 F150 King Ranch has about 40,000 miles on it and has never been back to the dealership since the day he purchased it!
Seriously, is it just me?! Thanks for letting me vent that!

Sorry to hear that you're having problems. After 11 months and about 17,000 miles, this is my first warranty repair. I can't really complain...no squeaks or rattles either. That would REALLY drive me nuts. I absolutely hate the thought of leaving my baby in the care of someone else. I also have an F150, a '97 model 4X4 with about 100,000 on the clock. Never had a warranty claim on it! No other repairs except for a new Pittman arm and a new driver's side power window motor. I did those things myself since it was way out of warranty. Still solid and tight as new. Can't say the same thing about my friend's GMC. I love my truck and have no plans to get rid of it.
