I noticed in your video when the car was running BAD that the Tach was pulsing when bucking. I would think that may be the TFI breaking down. I would replace it along with the PIP. Your problem seems to be Ignition. One other possible cause could be a ripped hose in the tank and its bypassing pressure. Have you had the tank down and inspected the sock and fuel line. Just a THOUGHT!!!

So swapped the dizzy with a known good dizzy and no good. I also made a EGR delete out of some mild steel I had laying around since I found out the EGR was leaking exhaust (unmetered air) into the intake.
Car still doesn't want to idle correctly and is missing/bucking/stumbling still.

Take a pair of vice grips and squeeze the BPV hose closed. See if it runs better that way. You may have a bad BPV.
I would like to see some pics by the BPV, VAM hose, and recirculation tubing.

Did a search (bucking and stalling) and came up with these... Ignition switch, orange ground wire at turbo.

Alright garry, I'll look for the ground (almost sure I saw it too). I'll grab a ignition switch from work tomorrow (also going to get a ECT sensor, just to see if that's a problem too).
I also made another video...

I'm almost ready to call someone and have them come fix it, I'm to the point where I NEED a car.

Will try that tomorrow (squeezing it closed). In the mean time here's some pics, you can see the piping setup in them.

Dude... if that's a Bosch bypass valve, which is what it looks like, it's in backwards. It looks exactly like the one in my wife's bug. Whether or not that makes a difference with that particular valve I don't know, but I would think that it would.

Here's the valve in my wife's car. The large blue hose is the intake hose. Smaller black hose comes from the IC piping.
