No power a take off.

Interesting..... I thought it was a post on this forum that prompted me to ask the dealer to flash my computer to get this new output..... I also thought someone had confirmed that they saw the message displayed. Ooh well, guess there is a disconnect somewhere. It would be nice though to know when the engine was in regen mode...... it would explain power loss, and would also prevent me from pulling out in traffic and expecting the truch to get up and go.

I'm still going to ask my dealer to check things out when I take it in for the recalls (still gotta make that appointment) because I really can't say as I have noticed the truck in regen mode since it's last service (about 4k miles ago), and I still think that it's been acting a little sluggish overall. I've also noticed an overall MPG drop since the last service (which included the software update). I was averaging ~15 MPG last summer and throughout the winter, and this past spring. It would vary slightly depending on how I was driving, but after the software update i've been much closer to the ballpark of 12 - 13 MPG...... I'm sure everyone is paying a lot more attention to this given the current cost of fuel, and 3 MPH doesn't seem like that big of a deal, but it adds up

OK, so I had a similar thing happen to me, but it was a little different. I was pulling a 10k trailer @ 65 and 35 PSI boost when the pedal had no response and the boost dropped to 10 and speed fell to 40. I turned it off and it cleared and drove 2-3 miles and it did it again. This happened 7 or 8 times w/o the CEL coming on except when restarting. On the last time, the CEL came on and wouldn't clear but the truck had all the normal power. I had the dealer reset the CEL and it is an intermittent injection pump problem or the wiring harness. This causes the engine to go into limp mode. I guess the pump operates at 20k PSI, but when it fails it only puts out like 5K so no boost or power. And mine only has 4600 miles on it....but it has a lot of other issues too!! Just my .02. Good luck, but I would try to get it to set a code and have warranty cover it.

The new flash is supposed to show when the truck is in regen mode. This is the first time I have seen anything mentioned about the filter message. I suspect you are going to see a CEL and the code will say you have a problem with the back pressure.

Ok I am curious too I just bought a used 6.4 w/ about 20k miles and it feels the same to me I just thought it was a dog of a truck. When I mash the go pedal from a dead stop it kinda hesitates and faintly puffs black smoke??? Do I need to reflash this truck with update? I need to know I already have an SCT waiting on delete pipe

[LBZinthehizhood]

Also will this require me to leave at dealer for a whole day? Or something they can just send a tech out to do in a few minutes?

Try resetting your intake under the hood the blue rubber button..

Hi all , I too now have a constant issue with power / hesitation. I've had my truck into multiple dealerships.I've not even had my truck a year. I have given up and contacted a lawyer. I'm done . I suggest you all having these issues look into the lemon law and keep your eyes and ears open. Good luck!!!!!!!!!!!!!

Well I did fuel my truck with LSD. Since I posted this issue I have now run 2 tanks of USLD. The truck now seems to be ok, and only did it once last tank, and has not happen since the last fuel up. I do add the cetane boost from ford every tank since I bought it new.

Is it true the new dealer 'flash' will notify you when the truck is in regen? My truck doesnt
