When accelerating and maintain a speed, everything is fine. When I totally let off the gas, its ok too. The problem is when I let off the gas just a little to slow down some, you feel a slight bucking. At a slower speed you feel a harder bucking at about 35mph or less, and slight is more around 65mph or less. The C02 sensor has been replaced. That didn't change the problem.
