Under startup I have a fine/light mist of white smoke out of both tail pipes that goes away. I attribute some of that to the month of March and the accompanying low temperatures. My concern is when I romp on the accelerator. Nice, thick, choking black smoke comes flying out of the pipes. It's when I floor it on the freeway or tap the throttle hard while parked. Not during idling and normal driving. The o2 sensors haven't been changed in 60 or 70,000 miles. That is also the mileage on the motor. I did just change the oil 3 days/200 miles ago and it's already looking dirty. What causes this, and where do I start looking for the fix? Any suggestions?
