Hello. From what you describe it would appear that your vehicle is experiencing more than one issue. P2070 is the code indicating the intake manifold tuning valve is stuck open. This may be linked to your performance issue. Dark smoke from the tailipe can be caused by a few things. The most common cause is due to an excessively rich fuel condition. If the vehicle is running rich, any fuel that is unburned in the combustion chamber can ignite while it is traveling through the exhaust system, producing black smoke. As your vehicle has more than one issue, I would recommend having the vehicle looked at by a professional technician, as the drive-ability of the vehicle is likely being heavily affected.
