1990 Lexus ES250 Black Smoke

My girlfriend was driving behind me on the way home from work this morning and told me that there was a lot of black smoke coming from my car. I couldn't really see it myself in the rear or sideview mirrors.

Where do I start?

    Black smoke= Fuel to air ratio is rich.
    White smoke= Burning antifreeze in the cyl.
    Blue smoke= Burning oil.
