I did some searches of the EGR, but found nothing related to my problem. I put on a Ranger manifold a few weeks ago, and couldn't re-use the egr pipe from my car or the rangers. Neither would reach. So I am running without the egr being fed by the manifold. I replaced the stock o2 sensor sense the connectors were too short to reach each other. I have new sparks too. The problem is, it likes to surge about a minute or two after start up, regardless of the enigne temp. It died once or twice too. Could the EGR be the cause of my problem? Thanks.
done a search but couldn't find what i need help with

It's possible. You've got two choices to fix the problem. You can remove the EGR valve and fab up a block-off plate to cover the flange and do away with the EGR all together, or You can do what I did. I took both EGR pipes and cut and welded them together to create a tube that fit the Ranger manifold to the Stang EGR valve.
Here's how I did it. I loosely attached the Stang tube to the EGR valve and let it sit. Then I attached the Ranger tube to the manifold and found where the two tubes run in basically the same spot. The tube I got with my Ranger manifold was bigger in diameter than the Mustang tube; big enough that the other tube fit inside it. I made a mark on each tube about an inch or so apart from each other to give some overlap and allow the Mustang tube to fit inside a ways. I cut both tubes, then fit the smaller tube inside the larger one, installed it back on the vehicle as one piece so that I could get the alignment of the two pieces right. I made a mark at the joint where the two pieces come together so I could tell how they were supposed to line up when I removed it for welding. I welded the two tubes together, slid one of the ceramic wraps over the new tube (to hide my ugly, yet effective welding
) and was back in business.

But the best part was he didn't charge me a thing. He even gave me a clamp to hold the smaller pipe inside the larger one. If the egr isn't at fault, I don't want to keep the car b/c I doubt I would have the money to fix everything. I just wish I had a carb'd set up sometimes.
Don't give up that easy. Parts are fairly cheap for these cars, and they really are easy to work on. You could certainly do alot worse. Like anything else, a little education goes a long way. There' s a wealth of information floating around the web specific to Mustangs.
Take it from someone who owned a carbureted 2.3, EFI is much better.
Glad to read you got the EGR pipe straightened out. It was pretty easy wasn't it?
