Okay, it turns out I DID have a vacuum leak, at least two.
One was where the 3hose connector for the vacuum lines that run to the smog, egr, and upper intake. If anybody remembers, that harness had fallen against the header a while back and melted most of the lines. I had thought I had fixed all the holes, and capped them good enough, but when I went to remove the harness today to clean up the engine bay, I found all three lines had holes in them from where they had melted. The red line that runs to the upper intake had come off of the harness completely. I removed that, replaced the red line (with the green one which was still good, lol) and capped off the others and that made a big difference.
The second one was the front and rear seals on the lower plenum. They were pushing out and leaking oil big time. I'm sure that was a vacuum leak too. I ended up just using a big bead of RTV instead of the actual seals (recommended by quite a few mustang guys).
Anyway, I put it all back together, and she didn't fire up. I knew it must have been timing, it only took two tries and she fired right up and was running like a champ! Unfortunately, I ended up shredding my belt (power steering pulley was out of alignment), and had to go get a new one. I got one one size bigger, and this one was just a little to big, and when I revved up the engine, the entire belt came flying off.
So here was the moment of truth. I pulled out of the garage to take it for a drive, and GOD she just RIPPED the tires off through 1st and 2nd (didn't hit it hard in 3rd, I was in town). Here's the best part!: I ended up shaming a Z28!
All in all it was a pretty good night. I still have some tuning issues, the idle drops real slow, and it's still running a little rich. I need to try messing with the afpr since the last time I did it, I had a big vacuum leak. Then I gotta mess with my injector slopes a little and a few other things and I should be good to go!!
Anybody visiting the Killeen/Ft. Hood area had better watch out!!
