Hi,
I have been stuck on this for a very long time now. so my E-250 has been having some issues when in overdrive going at about 45-50 mph the whole van shakes as if you would run over a 2 inch high rock over and over. when i disconnect the Throttle Position Sensor this problem disappears completely. I ran the dynoscan on the laptop and it marks the sensor to be 100% ok. i have change the oxygen sensors on both banks thinking it would be that but it wasn't i have been battling this issue for the past six months can anyone give me any suggestions?
Thanks in advance,
Fernando.

If you lock it out of overdrive, do you have any issues? Also, what it's year, I know in the mid-nineties, Ford had an issue with the overdrives.
