We're not talking about the accelleration lag, we're talking about the engine revving for several seconds with no power transfer. You simply cannot blame that on drive-by-wire because power transfer happens in the transmission.
As for accelleration lag, it's possible with or without drive-by-wire. With drive-by-wire Ford could have chosen to put a slight delay or require a minimum throttle input in order to give the drivetrain the illusion of a smoother start. However, do some research and you'll find many complaints logged in auto reviews for transmission lag on many vehicles with conventional accelleration. So, just because there's a lag in the F-150 doesn't mean that only drive-by-wire systems have it. (It also doesn't mean that the throttle programming isn't the only cause of the lag).<!-- / message -->

= regurgitating (that's funny)Dont worry about it, it happens,...When you need to get out of the way and can't because you truck doesn't respond like it should that is something to worry about, that's dangerous and an accident waiting to happen. When you hit the gas you expect to go, that's the whole point isn't it? There have been many close calls and accidents logged on this forum and others because of this problem, whether it's caused by the torque converter, throttle by wire or a combo of both.
i think that a lot of people have their own opinion of what might be causing a particular problem. It's just like the vibration/steering wheel nibble/bed shake, there are so many different opinions on causes/fixes that its mind boggling. Who's right/who's wrong, nobody knows not even ford. I don't think it is regurgitating sombody elses thoughts and opinions it is that many people have similar opinions on similar problems.

I realize I have the older style truck, but mine had these identical symptoms when I bought it a month ago. The more I drove it the more I disliked it. Took it back to the dealer for the shifting/ hesitation problem and they replaced the torque converter under warranty. Now it drives great! No hesitation in the throttle whatsoever.
