1993 Pontiac Grand Prix Questions

I noticed while checking connections on hoses and other connections that when I moved the vacuum line on the map sensor the RPM's shot up.

Every time I start my car it sets there and runs very rough putting out black smoke. I've changed Map Sensor, fuel pump and gas cap. Thinking about cleaning throttle body. It idles high at times.

I took the cap off the fuel pressure check port to see if it was getting fuel. I got gas and air bubbles. The motor is running very rough and is hard to start at times. Fuel pressure regulator checks good. I took off the vacuum hose and let it run 15 minutes with no sign of fuel.
