TROUBLE SHOOTING ENGINE

2000 Cadillac DTS

Engine Mechanical problem
2000 Cadillac DTS V8 Front Wheel Drive Automatic 68,000 miles

i disconnected the air flow sensor and removed the air filter box.I had to take out thermostat. Now I left the thermostat out and put everthing back together. Now the car is running ruff but the rpms are ok and blowing black smoke out of exhaust. What would be the problem?

Did you perhaps get the air snorkel dislodged after the mass airflow sensor causing unmetered air to enter engine, or disconnect/dislodge the MAP sensor?
