Throttle Valve
Ok.. Where's Vloney and Bowtie at?!
I just talked to another dealer.. This is what they informed me.. The 05+ has some Fly-by-wire setup for the intake which meant dumping the Throttle Valve.. On the 03-04 the Throttle Valve is required.. He said if you pull the plug it defaults and you get pretty much no boost (My problem).. Though he did mention that you can plug it in, disconnect the batteries and give it 30 mins to cycle out and clear.. Then all should be fine..
But based on my trips to my dealer for lack of power he said it sounds like the Valve was failing over time and me yanking the cord was enough to throw the codes and give the other dealer a reason to replace it.
So this is what has me REALLY confused.. Lot of ya'll said Ford disabled the Throttle Valve in a flash sometime ago.. This dealer along with my dealer says No, that the Throttle Valve IS required in order to manage the intake because the 03-04 don't have some fly-by-wire setup that the 05+ have.
Any ideas? I'm really wondering now.

I've got to wonder what in the heck a Fly-By-Wire setup is suppose to equivocate? Sounds like fabrication to me, but then I only drive a Ford...
I'm still hoping the best for you!
fly-by-wire: replacement of mechanical operation devices by electrical signals. The necessary force or torque is generated on the spot and is not transferred. So mechanical links or shafts are no more necessary. Advantage: less weight, more precision.
It avionics mumbo-jumbo

hmm thats a good point...the whole point of the valve is to create backpressure for the EGR i believe. but was taken out and deemed not needed (in 05+ models) but later flashes disabled it on 03and04 models...but i would like to know before i order my elbow....i will prob end up pulling the elbow to see if i even have one...ozx3+1 has a 03 and doesnt even have one.......so who knows...

well, i must know nothing then. if your dealer is saying that, either i am dumb or i misunderstood. well let me tell you what i know. the throttle valve was disabled early 03 flashing stratigies. the throttle valve is spring loaded to remain open at all times and the egr plate motor will close the valve. the theory was to flow more egr at idle with the plate partially closed. now, if the plate is closed, you will have no power cause your truck cant breathe, then again it probably wouldnt even run. all powerstrokes are fly by wire because the pcm decides how much injector pulse width is needed to start, run and accellerate. now, alot of things can cause no boost like sticking turbo, egr valve open ( not throttle plate ) and the list goes on.

exactly what i was thinking....throttle plate is only meant to work with the egr...but i knew it wouldnt cause a no boost problem unless it was not fully open and causing a loss of power. would could be confused with a bad turbo im sure...

OK, now I'm really confused. I was just getting ready to buy the 05+ intake for my 04.
Now I read this post!! What to do??
I guess the question is, is there any advantage in taking the throttle body off and installing an 05+ intake on an 04.
Cheers,
Neil

Then again sometimes you are stuck with an intermittant problem w/o any supporting 'digital' data; and perhaps you can't reproduce the problem.... nothing beats experience at that point.
Keep up the good work.

Same here. About to order the 05 elbow and I am going to remove the TB. If it is always open or dis-abled, it does not need to be there.
Aaron at intakelbows.com said "Get rid of it".
BowTie, what do you think the removal of the TB?

BowTieHtr,
Thanks, I value your opinion.
However, why even put the elbow on in the first place? That TB is just going to cause drag too.
I just figured to take it off. I do not care about the Ford warranty.
Thanks though. Now I am going to rethink it.
Well, that was quick. Thought about it. Gonna just take it off and put on the 05 elbow. Instead of throwing it in the trash, I will save it. If Ford wants to use it sometime in the future. I will carry it in a box, for them to put back on.

I got lucky. As posted, and now well know; my TB was just a brick, empty and devoid of goodies. I was very apprehensive even after I decided to take the leap and remove the TB and '03 elbow, replacing them with the '05-'07 rig. I rest a little easier now knowing the CEL will not glow on behalf of the TB.
I still owe you all pictures of the TB. Now my wife has the camera--with my pics on it--at her office. She's a stubborn woman! God love her! I know I do
