yes....its from not having cats......my car does that also. There is nothing to catch the carbon/smoke/oil in the exhaust gas anymore so it goes out the back (my driveway looks like I park B-17s on it....big black exhaust patches....kind of cool...
).
If you really think you are rich, don't try to lean it out without being on a dyno (wide band O2). I did this (thought I was really rich by watching the factory O2s at WOT) and today when I got on the dyno I was at almost 15 a/f ratio
