EGR & Emissions help, Trying to find a part # & advice. Options

[D-Man]

Okay, so my check engine light's been going on and off lately, and recently i (actually it was Ngofcukingway) WE checked the code, and it's saying that the EGR valve is failing. But it dosen't stay on, every 15-20 miles it'll go off for about 2-3 miles. So i don't think it's been a total failure yet, however i should try to do something about it.

First off, This weekend i plan to pull the EGR itself and clean the crap out of it, and hope that works, Otherwise I could use some other opinions/advice.

Also, I have no camera right now or i'd show you what i mean, but i'm missing (assumptionaly) a bung of sorts... Let me try to describe, then hit ya'll with a location.
*5sfe - on the driver side, between the Valve cover, and the Intake Manifold @ the Throttle Body area; there is a hose that runs between. This hose has direct access to control the EGR valve (Or some system component that allows the engine to run properly) NOT the line that some have running to the air intake (or back into the throttle body) no, this line is maybe 3-4 inches long, and is connected to what looks like a sensor of sorts... (sorry i have no camera w/ internet access ) Now, this "sensor" is pretty loose and bobbly; so i figure it should be placed in a "Bung" of sorts; and so with out it; It's my belief that the "Sensor" (or maybe it's a thru-tube; IDK - haven't had time to pull it) I believe it may be picking up excess Oxygen and telling my EGR that there is more Oxygen in the engines-air, so there fore it's double burning it. Witch would explain why the EGR is "Failing." It's doing it's job, But bassed on inacurate information; and therefore not doing it's job at all.

Does this make any sense? Or am i WAY fcuking off?

Here is where that "Bung" should be located



I cannot find a part number ANYWHERE for that darn thing... Does anyone know what it is?

Any ideas, opinions, advice, would be greatly appreciated.

To be honest i didnt try, but regardless if the senser was faulty, the car still didnt run right, it just didnt flip the senser for a short time because it was going out. Come to find out, sensers can wear out, they dont always just stop working. Anyways, Yah, its under the throttle body connected to the Block. I almost couldnt fit my arm in there to work, and i almost didnt have enought room when i was in there to get it off, it sucks a lot to get it off and its worse trying to get it back on.

What size Wrench is that to remove that hose? It's bigger than 22mm and that's the biggest my local oriley had to offer me
What size is it so i can crank that damn thing off?

Judging by the arrow in your picture and description it seems like you're missing the rubber piece in the valve cover that the PCV valve goes into, but I'm not really sure.

YES! That's the part number i'm trying to come up with. Anyone know?

On the GT theres a big tube going from the EGR valve thats mounted in the back of the intake manifold to the head (IIRC) and cleaning that tube does help.

While i'm at it, i'll give it a shot.

Thanks for the help so far guys, But i'm still SOL as of right now
