Cali Members, Get in Here! - Smog issue with possible error on 2007 Shelby GT Emissions label failed due to EGR

saldua · Mar 30, 2025

Hi Everyone,

Just bought my first Mustang, a new to me 2007 Shelby GT. I love it so far and I am looking forward to being a part of the community.

My issue is that I went to get it smogged, and I failed due to the EGR being removed/tampered with. After doing a ton of research, it looks like the 3v 4.6 does not have EGR. I tried to explain this to the smog tech, and he pointed to my Emission label under the hood, where it has EGR listed.

Could this be an error, or were the Shelby GTs made a little differently? I am leaning toward an error, as I looked at every engine bay picture I could find of a Shelby GT and could not see an EGR valve. Also, every manual I downloaded or parts catalog has no mention of EGR for the 2007 GT.

Any help would be appreciated. I am attaching a picture of the label. Thank you.

Yes. You at least [had] and EGR at some point, even if it's not there now.

07-14 Shelby GT500 EGR Delete "How To"

I recently completed my engine build and deleted my EGR in the process to make clearance for the return fuel system using a 2.9L Whipple. The EGR is in the way of the rear fuel fitting if you use aftermarket fuel rails and fuel line, so I deleted it and have received a lot of question on how to...

www.svtperformance.com

Shelby couldn't remove it even if they wanted to unless... They were putting out cars not suitable for road use.

that video is the Shelby GT500 which I believe had the 5.4 which did have EGR. Mine is the 4.6 3v same as the normal GT.

It will be tucked up under the intake on your car. Pass side, I believe.

Attached is an example of my engine bay.

I'm trying to locate a good image of your specific setup but I keep running into pictures taken with a potato and images of the wrong year(s).

Noobz347 · Mar 30, 2025

Your EGR will be the same as a GT of the same year.

saldua · Mar 30, 2025

Thank you for your help. Looking at a bunch of normal GTs and searching through threads I find people saying 3v 4.6 no longer have EGR.
I found a bunch of examples on Bring a trailer of the same engine bay and could not spot any differences between mine, other Shelby GTs and other normal GTs with respect to the EGR.

Here are a few pictures of a normal GT

other threads for reference as well. This rabit hole I'm going in is deep lol. I even found VEIC labels from same-year GTs that have no mention of EGR.

EGR delete

I went to delete the EGR system off the car and quickly realized it wasn’t anything like my 2002 lol…couple questions Looks like there’s a metal hose that runs along side the fuel line all the way up above the tank that’s hooked to the bottom of the EGR valve….can I delete that whole hose? I’d...

I have idle and detonation problems associated with one sticking/going bad... but ... I cannot find it

I look forward to hearing how stupid/blind I am... and where the FU%K it is!!!

Thanks!

The label attached is also from a 2007 GT.

I came across this while I was looking. No idea how reliable it is but it aligns with your suspicions:

Take a look at this:

Ford Workshop Service & Repair Manuals - fordrepair.info - 2005 Mustang Engine And Emission Facts Summary 4.6l-sohc

Ford Workshop Service and Repair Manuals, 2005 Mustang Engine and Emission Facts Summary 4.6L-SOHC

iihs.net

Click through the variants listed in the top/left corner of the screen and try to determine which of these applies to your engine.

Two of them list EGR valves while the other two do not.

I do not see where an EGR is [indicated] of any of those tags. Do you?

Noobz347 · Mar 30, 2025

Did the smog dude say which portion of that tag [specifically] indicated an EGR?

saldua · Mar 30, 2025

thank you again. EGR is listed on this label. below which is under my hood. The other label attached is under the hood of a normal 2007 GT.

saldua · Mar 30, 2025

Also I have found that workshop manual and there is no EGR listed in the label but if you like at the components list on the next page its listed on two of them which are Automatic variants according to other sources but not totally sure.

That is consistent with the info in the links above. The CDC2 and CDC3.

Now, the question is: How do you differentiate one from the other and figure out which you have?

Get one of those labels and put it on in replacement of what you have now.

The 4.6L 3V engine never had an EGR valve in any vehicle. The VCT performs the EGR function by retarding cam timing in certain situations.

Do you have a stick?

saldua · Mar 31, 2025

Yes it’s manual.

Everything I am reading shows that the 3v never had egr which puts me in this bind.

I was failed for “removing egr components” that never existed.

Spoke to a state ref and now they are saying I need to install it or it’s possible my engine was changed and they want to treat it as an engine swap all because the emission label list egr.

This looks like a mistake of labeling on Shelby’s end.
