A clogged fuel filter or a failing fuel pump would be my first guess.

Ran codes, 33, 44, 94. I don't have the air pump or canister anymore. Explains the 44 and 94. 33 is egr but cause this problem and didn't with the old distributor.

Has a brand new pump and filter. Holds 30 psi key off. Engine running 40psi with vacuum off. Turn engine off pressure holds. So no injector open. Possible a relay?

MSD = May Suddenly Die. There are more failures for MSD posted here on Stangnet than any other manufacturer,

Having said that, here's some diagnostic help...

You guys with idle/stall problems could save a lot of time chasing your tails if you would go through the Surging Idle Checklist. Over 50 different people contributed information to it. The first two posts have all the fixes, and steps through the how to find and fix your idle problems without spending a lot of time and money. Included in the first post is how to dump the codes, which may point to your current problem. I continue to update it as more people post fixes or ask questions. You can post questions to that sticky and have your name and idle problem recognized. The guys with original problems and fixes get their posts added to the main fix.

It's free, I don't get anything for the use of it except knowing I helped a fellow Mustang enthusiast with his car. At last check, it had more than 159,000 hits, which indicates it does help fix idle problems quickly and inexpensively.

As he said those msd dist. Are super unreliable . You may have solved your issue with the hot issue but now the dist may have its own gremlins . My car and others still have the stock dist making way more power just due to the reliability of it .

You could try returning it, but most places won't take back any electronic stuff. You might be better off having them fix it either run it, or put it up in the classifieds.

TFI module replacement time. They are notoriously bad, especially once warmed up.

Ok. Good luck.

Consider searching TFI module issues. It's good to have a spare, regardless. So, keep the one off of your old dizzy. Try swapping it on to see if that fixes the MSD. The MSD TFIs are common issues right out of the box. Maybe it's not your issue, but it really could be.

What they are trying to say is although the new distributor solved one problem it may have created a new one.
