Throttle plate removal
Hello,
I know you all are tired of hearing about this subject, but I would like more clarification before disconnecting the EGR.
I would like to know if it is necessary to remove the throttle plate after disconnecting the EGR valve. I have read through the instructions many times and it does not tell me that it is required or not.
Any information is appreciated.
Thanks

My EGR valve has been mysteriously unplugged for over 11,000 miles. The Throttle Plate has mysteriously remained in place.
IMO there is no need to remove the plate. As understand it...most have not.

You only need to remove it if you run a dummy EGR, but since you don't then don't worry about removing it.
I tried the dummy egr for off road and my check engine light was blinking on and off anyway, so I threw the dummy out the window and I think that I hit a duramax with it. Put a big dent in the side of the duramax too. Not really.

I keep forgetting about you left coast guys with special needs 
and the dummy EGR valve.
So you are saying that on the CA trucks if you unplug and remove the throttle plate the CEL will not come one?
But, why does the CEL care if the throttle plate is there or not after the EGR valve is unplugged?
It is very easy for me not to get this so thanks in advance for a simple explanation..

Throttle Plate and Dead Pedal
I found it to work best the other way around. I first "found" my EGR unplugged and noticed no difference at all and had the CEL on. Then I looked in the inlet pipe and "found" my throttle plate missing. WOW! What a tremendous improvement. From day one my truck had a fair amount of "dead pedal." Rolling along at 5-10mph when you hit the go pedal the truck would do next to nothing for what seemed an eternity. Almost got hit in an intersection once because it took the truck so long to accelerate, scary. Since "finding" the plate removed, NO MORE DEAD PEDAL! The truck responds all the time, every time. After all this I "noticed" that the EGR was plugged in. No loss of performance and no CEL on either.
My thought is that when the plate is closed and you hit the go pedal, you have to wait for that little actuator to open the plate before you get boost to get you going. Just my $.02.

kb1aah..your experience has not been the norm...outside of CA anyway. Matt (PSD 60L Fx4)...our little buddy in the Carolinas is our resident expert on this. Maybe we can get him to chime in.
In any case if you want to know more regarding the WART, as I affectionately refer to it....please go to the tech folder in the 6.0 sticky section. There you will see much discussion of the EGR valve.
Be sure and read it all because some thoughts change as the thread matures.

Wonder if that could be why mine acts differently.

Ahh. A horse of a different color it is. 
So maybe I'll look into the option of getting an addtional EGR valve to plug in to keep the computer happy. Then again if there is no EGR flow the light may still come on. Has anyone with a CA truck been successful in turning off the CEL by using a second EGR valve? I am currently browsing the EGR disconnect thread.

how do you know if you have a plate or not? My enigne was born on 6/03, all the senors are there and on the outside it looks like there is one, but how do I know unless I take it apart to find out? Also will I need to put it back in befor I have any work done at the ford house? I know that this is an old thread but thought I would give it a try.
thanks all for your time,
Steve

The easiest way to check for the throttle plate is to remove the four allenhead screws that hold the inlet elbow down (inbetween the radiator and the oil/fuel filter housing) It looks like a huge carbuerator butterfly. two screws to remove the throttle plate --check the tech folder-be careful not to drop a screw in the plenum.
