A flashing check engine light is a critical indicator. That usually means that something went wrong that will damage the emission control system... and that is usually an ignition issue. First off, the OEM plug your car calls for is an NGK irridium... NOT BOSCH and not anything with more than 1 prong. Those NGKs are like 2 bucks and they are the proper plug. Make sure you have these plugs and make sure they are gapped to .028. Next, my suggestion is put all the new stuff on again. Drive it to autozone and have them delete all the codes. Drive it around until the check engine light comes on again, then immediately go back and read the codes. The ECU is smart enough to know which cylinder is misfiring. On these cars, I think they have three banks of two... meaning one "coil" inside the coil pack operates two of the cylinders. So if you get multiple misfires, it's the coil. If you get one misfire it's probably an individual plug wire or plug. Good luck.

Are there any fault codes in the ECM? No "Check Engine" light on?
Black smoke means it is running rich. You should be getting Rich O2 sensor codes. Running rich is usually caused by the Mass Airflow Sensor. (MAF) This is located in the snorkel that connects the air filter to the throttle body. Make sure that the snorkel hose is properly connected to the sensor housing as well as the throttle body housing. (See Picture)
Also be sure to check the reference voltage (VREF) to the MAF, MAP and TP sensors. It should be right at 4.8 to 5.2 volts. If it is low, suspect a shorted sensor. Note that several sensors are served by the same VREF circuit. I had one GM 3.1L engine that was running like **** and smoking black that had only 2 volts at the MAF. I started unplugging sensors to see if the VREF would come up to specs and found that I had 5 volts at the MAF with the Coolant Level sensor (in the radiator tank) unplugged. Replacing the Coolant Level sensor fixed the car. Any of the sensors could cause the same problem if it is shorting the VREF circuit.
If the VREF circuit checks out OK, Then I would Try a MAF sensor
If you are getting misfire codes, you probably have an injector sticking open.
