nothing wrong with 26 lbs of boost that is a normal number for a stock truck


the only thing that doesn't point to a oil feed runaway is the fack that the truck shut off with the key IMO

 

having delt with a few "runaways" over the years..
I will tell you the best and safist thing to do is put the truck in nutral, pull over and take the key out. walk away from the truck. the plume of smoke will surly get passerby's to stop/look.
the best way to really shut one down is a CO2 based extingisher... aimed at the zodad mod

 

The dealer spent 5 hrs getting it to act up again and said the accelerator pedal assembly needs replacing, along with the FICM (fuel injection control module) 400 for the accelerator and another 900+ for the FICM. I told them Ford had to work with me due to creating an unsafe condition, The fuel injection and egrs...has been messed with about every 6000 miles since I bought the truck. I think they should take care of the bill entirely. Any opinions?
With all the problems with the EGR cooler replacements, head gaskets and now fuel injection, along with safety concerns I am thinking about going legal. Its something I think is cowardly but may resolve future issues.

 

Truck is fixed, anyone need a throttle pedal assembly...no warranty!

Still scared that it will take off again when I least expect it. Dealer took care of the throttle pedal and labor, I paid 820.00 for the FICM.

 

holy crud
what was the root cause the pedal failing to spring back up ?
it would seem impossible for the pedal to give a falls WOT output since there are three senders in it that the PCM checks for validity

 

there is a knowen issue with 7.3 pedalsthey all make you get stuck in idle only. when they fail.

 

The assembly is made in the same factory as the Toyota was. It is all electronic and still can't believe it was the root cause of the "runaway" I experienced twice now. I am towing a 38' toyhauler tomorrow and in hopes it doesn't act up again. Ford has had issues before but not well documented when researched on the Internet.

 

can you please provide some proof of that statement. I have not heard or read it anywere.
thank you

 

The only feasible way the pedal assembly could cause a runaway condition is for the pedal to have failed physically, not electronically. I can believe that a physical failure, like a stuck pedal or a broken spring, could cause a failure. But I don't believe an electronic failure causing a runaway is possible.

Consider how the APP sensor works. There are three potentiometers built into it. The service manual refers to them as tracks. Each track is fed +5v and returns a voltage based on the position of the pedal.

APP1 varies from ~4 volts at closed throttle to ~.75 volts at WOT. APP2 varies from ~1.5V to ~4V. APP3 varies from ~1 to ~3.5V. Note that APP1 is inverted from APP2 and 3. If one of the APP signals disagrees with the other two, a code and the CEL is set. If all three APP signals disagree, the PCM defaults to idle.

The only possible way for the APP to fail and cause a WOT throttle condition is for APP1 to fail to .75V, APP2 to fail to 4V and for APP3 to fail to 3.5V ALL at the same time. While this is technically feasible, it is very, very unlikely.

 

IIRC it's been proven (and NOT by Toyota) that accelerator pedals and electronics were NOT the cause of the so called toyota unattended accelerations.

 

I read more on this when I was researching it that went into more detail, However this is one of the easiest sites I could find about it.
Consumer complaints about Ford F-250/F-350 Pickup

There is also a company called CTS Corp. that makes them. I am not sure of all models they produce them for Ford. The safety risk here is it is simply a drive by wire technology that has no control like cable linkage if it fails.

I can easily understand why it is hard to look at a pedal assembly and believe it alone has failed. I think it is something with the ECM or other that is causing voltage or circuit issues. Until NASA and others pinpoint it we are all risking the "drive by wire" risk instead of a cable...sometimes technology really sucks!

 

The page you linked says there are 13 pages, but apparently you can only read one. And not a single one of the complaints is about runaways. Not very convincing evidence.

Ford has been using drive by wire technology since the introduction of the 7.3L Powerstroke in 1994. If there were a problem, I think it would be pretty well known by now.
