Answer
Hello and thanks for the question...I'll try to help.
 First......are you absolutely sure that it is smoke from running too rich and not a coolant leak internal to the engine?
 What I woiuld suggest you do is pressure check the cooling system and also put a gage on the fuel system. Also, check the return line to make sure that it is not kinked or blocked.....this will cause high fuel pressure.
I would also suggest that you scan the computer system for fault codes.
Hope this helps,
