1G Trouble shoot assistance needed

[Alpha D]

When i finished checking for vacuum leaks. The car was started up again. It idle below 600 wanting to stall out. After slightly adjusting the BISS screw. Shutting the car of for about 30mins inspecting for potential hoses that could not be connected. Everything was connected properly. I started the car again and it idled at 1500. The car continued to pour smoke. The black fluid continued out the exhaust as well. The texture of the fluid does not feel like oil. It has a strong smell of gas as well.
