One of the most common causes for excess fuel use,the fault code that has set here and smoke is one or more of the fuel injectors leaking down into the cylinders.I have had to replace several of these before for this fault here.If you have not had the fuel injectors tested to see if one or more are found to be an issue this needs done.You only need to replace the injectors that are at fault here.
