Can any one help with a vibration that just started on 2002 Escape? V6, automatic, 4wd, 130,000 miles. vib comes in at about 60 and continues as long as I accelerate. If I let the car cost the vib goes away. WHen I step back on the accelerator the vib is right back there. One tech told me it might be the drive shaft and another told me to have the torque converter serviced. Anyone have a good guess on which way to go?
