I hooked a voltmeter to the vcc to a chassis gnd i get 5 volts with the key on
I have continuity from the gnd to the chassis
I hooked the voltmeter to the map output and i get 3.5 volts with the key on with or without vaccum.

The output never wants to change... so
Bad map sensor?

Looking for a second opinion before i go get a new one.

you can check the spec in the honda hanes book.. or whatever you call it.. i have it at home.. but i wont home until friday. do you have check engine light? usually when the sensor goes bad the check engine light pops up

maybe a bad voltmeter. im not sure but i dont think the vss should have 5 volts when its not doing anything. why are you checking this?
