I would say you have a wire going to the map sensor thats close the map sensor that is bad. Probably the copper wire is broken inside the insulation. To me thats the only thing that makes sense at this point.

I missed a word close to the map sensor. Meaning when you unplug or plug in the map sensor connector you disturb the bad wire.

I understand now. One I mit have a bad wire or two I have a bad plug. So what you are saying is test the wires when I move them around and test that plug to see it one breaks the connection
