The car: '94 Caprice Classic 5.7L / 350 cid MPFI
It runs great until it gets warm then it spits gobs of carbon out the exhaust and starts sputtering and stalls (flooded). forget going anywhere then :(
Gobs of carb cleaner. Checked several fuses. New Plugs and wires. New Mass Air Flow sensor. Many large tears.
Any ideas guys?

if it suddenly goes rich when it reaches operating temp (warm - i.e. closed loop operation) then it's likely the o2 sensor is faulty, since it is used as a measurement of lean/rich condition only when the car reaches operating temperature.
