The only time that I've ha the wrench come on is when I had forgot to put my program in the truck and my turbo built up about 40+ psi of boost. Got a strange reaction from the truck, really hard to describe and then it was like in "limp mode". I knew it was because of too much boost though. However, since you said the truck runs fine, I doubt it's that unless I just over reacted about "limp mode".
I wouldn't know where to begine though on this without looking at the codes to see, even if it's just in general, what is going on with the truck.

Wrench is really serious.
Take it to the dealer and at least, get the codes read now.
It can be things like failure of the accelerator pedal.
You don't want to go Toyota.

Go to the nearest place with a scanner to lend you... see what it reads.
Then, as warranted.. go to the nearest Ford dealer.
Really --- have it looked at.
I am the king of logging and deleting CEL codes... and I don't ignore the wrench light.
AFAIK, the wrench light may automatically mean you are in "limp" mode...

Find someone with a good CAN scanner that can read more then just the general powertrain module. What would show up on an autozone reader(if anything) might just give you a general indication. Better then nothing, but it could still leave you wondering what it is.
From my one experience with the Wrench light, I would say that it's limp mode til it gets fixed. Could be wrong, but based on my experience, I was in limp mode when it came on for me.

It's not as serious as folk are making it sound; the latest flash uses the "wrench light" to notify the operator of several "out-of-spec" readings that could lead to typical major 6.0L problems. 1-FICM low voltages (FICM Failing), 2-Oil Cooler Efficiency (EGR & Oil Cooler Replacement), & 3-Turbo Overboost (Head Gaskets). If no hard cold starts & you are just driving normally when the light comes on ... suspect the Oil Cooler Efficiency.
If you were not gitting it before the flash, then there's your answer.
Also, I got a fancy CAN enabled code reader ... but it still will not retrieve the disappearing "wrench light" code. It's gotta be stored somewhere ...

Can you tell me what month / year flash started to do this?
That way, I can make sure I don't flash again until the OBDII readers catch up with it.
