You could have a leaky injector. When mine had a bad fuel pressure regulator it would smoke black while idling, a bad regulator will allow fuel to flow into vac tube then fill the intake till the pressure is gone.

Now, have you checked all your diff, transmission, transfer case levles and fluid condition yet?

Greased everything that can be greased while visually inspecting the components?

Checked brake fluid and power steering fluid condition?

Remove the plug. The level should be at the bottom of the hole. Stick your finger in it and get a sample.

Transfer case same way.
