Help, 05GT doing something weird..

I love this car, really, I do.. but it has a little issue that is
getting more irritating as the newness wears off.

On the highway, when I drop it into fourth and floor the throttle, it
revs up and engages just fine, runs wide open for a second or less,
then cuts out as if I take my foot off the pedal completely and
immediately engages again to full accelleration.. It's never more than
a second after I floor it, and never lasts for more than a measurable
blip in time. The resulting jerk of this feels painful for the
transmission and my neck as well.

It never does it in 1st or 2nd, only on the highway when dropping to
4th or 3rd. I have had it happen both when the traction control is on
and also when it is off. It's not just as if I lift on the pedal a
little, it's definitely a complete drop in throttle.

Any suggestions greatly appreciated!

Dude,

THIS is why most REAL drivers use a stick!

I think it may be something with the injector or/and computer. Have
your dealer take a look.

I never understand why someone would spend the money on a muscle car
and not go manual. (The only excuse is if you get one of those sweet
Lightning trucks).

Cheers,
Johnny

Hmmm, 5 speed, 2005 and your having a problem. Not to be an ass but don't
take the advice of amateurs (I realize not all of you are) take it to the
dealer! It's under warranty!

I've had a similar problem when leaving a stop. Car starts to accelerate, cuts
out (quick jerk) for a half-second, then picks right up again. It's happened
twice and is one of the things I'll tell the dealer when it goes in for the 5000
mile service.

Seems Ford programed a little "Lag" into the fly by wire throttle to
keep people from mailing the motor revs too much. Check out this thread.
