RUNNING ROUGH

Toyota Pickup

94 toyota 4x4, 22re, 157000 miles. Coming home from work my pickup " stumbled" then started running very rough. It is running very rich as evidenced by black smoke coming from exhaust pipe. No fault codes were detected. Seems to run a little better after sitting overnight(cold). Any ideas on what could be causing this? Vehicle was just emission tested last week and passed. Thanks
