You have a fuel injected car. Things that can cause too rich would be a bad altitude sensor like the map or mass air flow depending on which one you have.
Anything that would cause excess air to go into the exhaust system like a cracked exhaust pipe before the 02 sensor, or low compression, or a stuck open pcv valve, intake gaskets, throttle body base gasket.
Or a Throttle position sensor which is telling the computer you foot is on the gas when it is not.
Its possible you have a bad PCM,, or coolant temp sensor saying the motor is still cold as its warming up.
Its possible you have a vacuum hose somewhere on the engine with a big crack in it or its just inplugged and you dont see it.
But my first guess would be possibly a bad computer.
Try creating a big vacuum leak when its loading up. It should run better.
Also if you have an egr valve it could be stuck open a little causing excess air or an idle air control valve stuck open.
Does it clean up if you rev it up or does it blow black smoke reved and at idle. This could point towards the altitude sensor.

i just had the same problem on a 1997 4.0 . crank sensor is most likely bad you can spray starting fluid in the intake tube and car will start meaning you have spark but injectors will have no power I.E. crank sensor is bad 38.00 dollars at local parts store dealer told me 170.00 dollars make sure you push it all the way in when you install it i just posted a fix for this on this site today . after you start the car if it gives a misfire code and check engine light comes on loosen the crank sensor bolt and push it in again then tighten the bolt the cardboard on the sensor for the air gap wares off a little bit enabling you to push the sensor in a little bit more misfire should be gone there is only a few thousands of an inch adjustment for the air gap and it makes a difference. hope this helps
