Car stalls when mass flow sensor is activated

I have a 1982 928 Porsche that stalls when the air intake mass flow level opens and I would highly appreciate any suggestion on what I could try to fix this.

I had to take the engine out to do some repairs. The engine is now back in and the car runs great until the mass flow sensor is activated. When I put the entire air intake on the side with the mass flow sensor connected so the air doesn't have to go through the air intake the car runs fine. However, if I manually push the air intake level down the car stalls immediately even though it is not attached to the engine and no air is going through the air intake so I believe the mass flow sensor gives a wrong signal to make the car stall.

The only electrical I touched when I took the engine out was the 14 pin connector located in the front on the right hand side under the hood. The connector came apart and although I put it back together I'm not completely sure if it is put together correctly since it seems that many of the wire colors do not match up. It was only the upper side of the connector that came apart. I would appreciate any suggestions.

Peter
