2002 V40: Engine Shakes Under Load

[v402002]

I have a 2002 V40 with about 235,000 miles on it. The vehicle shakes under load between 50 - 70 mph but if you let up on the accelerator it smooths out quit a bit. When it shakes it feels like it might be a front end issue but you can't feel it through the steering wheel if it were that problem. I pulled the codes and found p0107 (map sensor) and replaced the map sensor, the vehicle runs a little better at low end speeds but the high end speed shaking is still basically there. I've heard that it might be because of a bad motor mount. I give the engine gas at idle but don't see the engine move around at all. Has anyone ever had this situation? Thanks is advance.
