when the car is started it has a rough idle almost like a big cam lope and black smoke comes out and it smells really rich and the service engine light comes on. Once the car is warm, it runs smoothly, but once it is shut off it will do it all over again. It is throwing a code 34 wich is a MAF sensor I have replaced the MAF sensor, O2 sensor and the EGR valve and still the same thing. What is happening?

I have a similar problem. I have a 1989 IROCZ with a 305TPI and it also has a rough idle and smokes at start up. I also have a check engine light on. I have replaced the oxygen sensors, egg valve pcv valve, TPS sensor, IAT sensor, water temp sensor, did a complete tune up and still runs bad.
