Any Ideas - Truck Down

really...so by that theory everytime the valve opened the
truck would quit running...

Thanks bush, now I know about the EGR system. So in theory by unplugging the egr would that then allow me throttle to get finished with what I was doing and enough safe time to get the truck to the shop? So I won't be left stranded on the side of the road?
I will have to say it again, bush I just don't think there is anything you don't know.

im flattered but one thing is certain i dont know it all...
you can unplug the egr, do it when the engine is off
to ensure the valve is closed.
some have disconnected their egrs and never plugged
'em back in...im not particularly a fan of that as a solution,
but i wont go there.
depending on your truck / year (and if its a california based
truck for sure) you MAY get a check engine light or service
engine soon (cel or ses) light on the dash...and you will
get odb2 codes <set>
personally id like to continue to hear if your truck remains to be ok.

don't worry bush, I will definitely be on here if I ever have anymore troubles. As of right now though the truck is still running fine. At least now I know that I can unplug the egr and get the truck to the shop without have to call for a tow.

Do tell, Bush. Some of us have over 230,000 without a functioning EGR. And still running the original turbo. On the original engine. Whats the downside?

im not qualified to answer this...so ill just give you my opinions...since
you asked
down sides are engine codes, CEL/SES's and potiential egr cooler
build up...my thoughts are its there and it better work...or ill be
takin' it up w/ ford & the dealer.
I agree it "should" work. More often than not it doesn't. There are as many posts on these boards about egr problems than anything else. There have been a multitude of posts about how to field strip and clean the things. I have even read about owners carrying a spare, or having 1 connected to the plug, but just laying in the engine bay so it couldn't clog. I'm going to go out on a limb and say that the longevity of these engines could be affected by the egr. I realize its part of an emissions system, but I can't wrap my arms around how pumping spent gases back into a fresh fuel / air charge is helpful. Or good for the turbo. Not to mention the soot thats heading back to the oil. No thanks.
attaching an egr (externally WONT WORK) because the egr action
SHOULD have effect on other senors down stream...when the egr is
commanded to open or close other items expect to see the results and
take other positioning action based on the results.
carrying a spare isnt so bad, (when you consider how easy it is to replace)
although the only one ive had "fail" in 70k miles was the 1st generation
(weak stepper motor model)...and even then all i did was unplug it til i
got home & could diagnose it.
7.3L folks have carried spare CPS's for years...(at least we can
unplug the item in "question" that seems to be causing the most
problems for 6.0L owners)
egr valves themselves seem to fail in increasingly RARE numbers
<since they updated the stepper motor to a heavier unit> if anything
egr COOLER cracking seems to be a more critical re-occuring
issue...and almost always the egr cooler replacement reveals a restricted
or blocked oil cooler. (ive said it before...RUN A COOLANT BY-PASS FILTER) !
i agree recirc. cooled SOOT doesnt seem like a good idea for things
like passages and turbine vanes (vari or otherwise)
