Sounds like an oxygen sensor problem. O2 sensors have to be warmed up to around 900 degrees to properly operate, so until they're up to temperature, the ECU ignores them and fuels the engine on preprogrammed fueling maps stored in the ECU. Once they're up to operating temperature, they provide feedback to the computer for properly fueling the engine. Blowing black smoke indicates a rich condition (excessive fuel), which usually is the result when and oxygen sensor is defective. The computer realizes the O2 sensor isn't working right and goes to a rich-fueling map for the engine. Rich running is not damaging, other than it can foul spark plugs and (if untreated for a long enough period) could clog the catalytic converter. This is better than a lean condition (too little fuel) which superheats the cylinders and causes them to detonate, which can fatally damage the engine. I would change out the primary oxygen sensors and see if your problems go away. You may need to get new spark plugs as well, especially if this has been going on for awhile - they may be carbon-covered and not firing efficiently.

It sounds like your thermostat is broken. The metal retaining tabs that hold the thermostat together can break over time. I would recommend pulling it out and checking it. When installing a thermostat there is an arrow on the edge. Make sure it points up. toward the top of the cylinder head.

It could be one of two thing's, first idle-air bypass valve located on the throttle body ( Follow the hose up from the air filter, it goe's to the throttle body ) the idle-air bypass valve is bolted to the throttle body with two I believe 8mm bolt's, with one electrical connector going to it. The next could be the MAP sensor located under the hood upper passenger side of the fire wall this is also held in place with two 8mm bolt's and has one vacuum line going to it, hope this help's you.
