"stuck" throttle
I have had this problem for about a year now but the dealer does not believe me. It seems it's happening more frequently now (probably on the order of 3-5 times a week.)
It happens in reverse and drive. I'll hit the gas and let off but the throttle stays high. It's not so bad to the point it's dangerous, as long as I'm not a moron. But it happens alot. It only happens on light throttle, like moving the truck forward a few feet or something like that. I have to quickly hit the brake and move the shifter to neutral for it to go back down. It does not rev that high but it certainly does it. I would say it goes to about 1500 RPM. Again it's not so bad it's dangerous but it's happening more frequently. Anyone have this issue?

When backing up to hook to trailers sometimes I need to give it just a nudge. So I will tap the throttle and it will bump up in rpms.
After I tap it and it moves just a pinch I put it in park.
the rpms take a second or two to come back down sometimes. I think that is what you are decribing.
I think it is programming/emissions related strategy. I find it no big deal or a problem.

08 6.4 throttle problems
I have an 08 F250 6.4 that the throttle pedal has dissapeared on me twice while taking off from a stop. The first time it happened I thought I had did something wrong. (like the floor mat got hung up or something.) But the second time there were 3 other people in the truck with me and the throttle was actually all the way to the floorboard. Both times this happened the RPM's went to about 4400 and I had to put it in neutral and turn off the engine. Then the pedal finally came off the floor. SCARY... Ford dealer says that there isn't a problem!!!! Finally convinced them that there is a problem now I am without my truck waiting for an engineer to come out from Ford HQ to look at it.
Any one else having this issue. Ford says there are no other complaints about this...
HELP...

It did have the overspeed code but nothing else. Ford Garage is telling me that this is impossible to have happen as there are too many safety factors involved. "isn't that what toyota said".

my truck does the same thing, if I'm just backing up or going forward at an idle and lightly stab the throttle, it'll stay up on a high idle. it goes back down after a few seconds, but it's definately weird.

You guys are describing something I had experience with too. I think on the 6.4 that if you are in the right conditions, you can tap the throttle and make it go into elevated idle while in R or D. It felt to me like it was supposed to do that so you can "idle" your way around if you want.
Usually happened to me when hooking up to a trailer, normal idle sometimes is not enough to move the truck in gravel or unpaved land. One of those things I never really thought about. I wonder if it is actually a strategy programmed into the PCM?

I have a 2008 F-250 that has had the exact same "stuck accelerator" issue. And of course, the dealer cannot find anything wrong with the truck, nor can we recreate the "out of control" acceleration on demand. Has anyone heard that Ford is acknowledging that there is an issue out there and has an idea?

I have had that happen a few times...seems to always be when backing out of the driveway. Probably happened a half dozen times. Its never been dangerous...but it is noticeable. When I took my foot off the gas, its like it left me foot right where it was.

Stuck accelerator
I had part #8c3z9725a pedal assembly replaced on my 05 F350 after almost plowing in the back of a sedan loaded with kids. Friends at LHM ford in Salt Lake took care of me after Ford would do nothing at 55K miles on 5/5/2011. It happened once before and had to go to neutral and shut it down to reset. Filed a letter with the National Highway safety for what it was worth. The original assembly was built by the same factory the Toyota's was in, the new assembly was a complete different style except for the mounting holes.
I was mentally scarred after seeing the kids faces ahead of me. The truck had went from about 30 miles an hour to about 65+ before I could do anything.

Seems this is a fairly common happening with the widespread usage of drive by wire systems. Look for codes, check UR electrical connections, change the accel module first than the throttle body.
