What seems to be happening is when you are driving the engine seems to be bogging down, but seems to be just fine when in park or nuetral. When you let off of the gas the bogging goes away. When you get in the gas and the transmission down shifts it goes away. Could this be a fuel filter or fuel pump problem?
