Cadillac Repair: 1981 caddy, baro sensor, filter screen

Question
i got a 1981 caddy coupe i replaced a baro and map sensor and everything got better but now it blows black smoke. but when i take the vac hose off the map sensor it stops blowing black dont really know whats up with that. and when i replaced both sensors only found one hose to the map sensor but the original baro sensor had  a nipple also but no hose.(is there suppose to be a hose for that one too?)

Answer
Where did you get the new MAP and BARO sensors ?>

There is NO hose that goes onto the BARO sensor. It is supposed to have a small filter screen on the BARO sensor.

Are these USED sensors and are they the ROUND metal style or the newer flat black plastic style ?.
