Well I unplugged the AFM and the car ran even worse. I could NOT rev it with the AFM unplugged, every time I touch the pedal it dies, and it didn't even want to stay idling. With it plugged in I am able to rev it.
Bad AFM electronics or something else?

Do you have the answer? Because I can't figure out whats wrong with my car, and no one else can either....

Pull the EFI fuse for 30 seconds and drive it so it doesn't work.

After you fix this problem, and the giant intake leak you seem to have.

I took the entire intercooler system off today and checked it over. Everything looked perfectly fine and I put it all back together tight. Didn't find any leaks, and the car is still running the same. If anything in the system would be leaking it would have to be the gaskets between the intake manifold runners which I can't see. I'll have to wait and get a compressor to do a full boost leak test I guess. So you think its a boost leak Nick?
You already told us long ago it didn't run properly with the AFM disconnected. That was my point. Even if the AFM is fixed you still have problems elsewhere. This reason its on post 89 is because the OP has weak trouble shooting skills!
Im talking about the intake the is attached to the side of the engine bud. Upper and lower plenums. Make sure they arent leaking

And a lot of you have weak helping skills. I may have weak trouble shooting skills in this instance but I'm going by what my car is saying to me and by what the TSRM is saying. If that's not a good way to do it then I'm sorry because I'm actually trying really hard to figure this out and work my way through the problem. I'm done taking the criticism over this. For those of you who have really been trying to help me I thank you ,and we will continue working on the issue. However, I am done with this thread, and will most likely never post another issue on Supramania again.
Boost leak? I said intake leak. Your main repeating symptom shows a lack of fuel enrichment. That could be the airflow meter, the pump, or false air unmetered air. You have to find what it is. Then the other possible problems.
I wouldn't say lack of fuel enrichment, In fact the opposite. The car is burning fuel like crazy, at least on start up and idle.
What about during a big boost leak? The car runs really rich then and will stall when you open the throttle.
Hard starts, runs rough and no power is something a bad egr could cause. Not sure if it could cause stalling but I have seen weirder things. It's worth a try. I could be completely wrong but what do you have to lose??
You can use 2+2 to check intake leaks just spray it around the intake while the car idles and it will rev up if a leak is present also vac lines as well.
