I took my mass air flow off . But before this my car was running perfectly fine I just wanted to replace a hose so I unplugged the mass air flow and got everything done I go to plug it back in and my car starts and dies so I bought a new mass air flow and it still doing it I don't understand why it would do this if everything was working before hand
You still have a vacuum leak most likely.

+1. The car's 20 years old, all the rubber is crunchy and fragile. When you move some part of the intake system, it's very likely you'll rip it, and cause a big intake leak. After checking all the pieces you moved or touched, you should get the car to a good BMW/Euro shop, and get a smoke test of the intake / ccv system. Oh, and return the new MAF.....it's probably Chinese Autozone garbage anyway, and the 20 year old OE part is likely more trustworthy. (Never buy non-OEM sensors)

Sounds like a massive vacuum leak. There is a resonance chamber hanging off the bottom of the rubber boot between the throttle body and the MAF. I'll bet you disturbed this.
Oh, PM me if you'd like to buy a known good used OE MAF, I have a few around.

If you can leave two black stripes from the exit of one corner to the braking zone of the next, you have enough horsepower. - Mark Donohue
