Hesitation on accel? F-150 TSBs?

[Coiled03]

So I recently bought a 2007 5.4L F150, and I've noticed that sometimes on medium/hard acceleration it hesitates pretty substantially, to the point that I can see it drop a good 250rpm on the tach.

I've researched this a bit, and from I've found it's not an uncommon issue. What I'm wondering is, does anyone know if there's a TSB, or recall of any kind for this issue? If it's so common, I'd expect there to be one, but I can't find any. Also, does anyone have a remedy?

TIA.

EDIT: On another note, anyone have a suggestion for a good site for F-150s, ala SVTP.

I have a 2005 F150 (purchased new) with the 5.4 that had the same problem. I think it's a symptom of the "throttle by wire" system. I installed an Edge programmer and that cured the problem.

ford-trucks.com is pretty good.

had the same problem on my 07...superchips tuner solved it... I spoke with my dealer numerous times... They claimed they did a recal...it seemed to help a little. its almost dangerous.

I've heard a few people having problems with the TPS (Throttle Position Sensor). Others have needed a tune to get the feel they were looking for.

F150online is a great forum.

The throttle hesitation is caused by the fly by wire. Ford has a flash out for it now, although it doesnt cure it 100% it is much better. Ford wont tell you this but a majority of the name brand hand held tuners do cure it 100%. Find yourself a dealer that carries Xcal's. If you buy it from them they wont void the warranty when you install it.

So, how do I get this "flash" you speak of? Do I just go ask for it? I'm not gonna buy a tuner just to get rid of this. It's not that big of a deal to me. Some improvement would be nice, though.

Go to the dealer and tell them your aware of the new flash for your truck and you'd like to have it performed. They will run your truck and check to see if its been completed. If it hasn't then they will do it. If im right i believe there's a TSB on hesitation, I cant log into Oasis at the moment and check.

That's what I'm sayin'! If I could get a .pdf of that thing, I'd be at the dealer this afternoon.

It was a TSB. I had mine done with a reflash. It came back though. I am going to try a programmer one of these days.

So far I have learned to live it.
