I am a pretty well educated shade tree mechanic, have been wreching on cars since I could walk, and I am also a part time parts guy for the local parts store. I have recently purchased a 1993 Ford Taurus SHO 3.2 ATX and the car has a few problems that I believe are related to the Vehicle Speed Sensor. First of all, while driving at any speed, the assist form the power steering changes and causes what feels like a jerking in the steering wheel. Secondly, the trans holds gears until about 3000 rpm before shifting and downshifts rough when coming to a stoplight. Third, when at cruising speed, the trans does no downshift under heavy throttle. Fourth, the O/D cancel switch seems to do nothing. And finally, when the car fully warms up, it tends to stall when coming to a stop, almost like the Torque Converter Clutch is staying engaged, that is if it has one. Idle quality also seems to be affected after warmup, with the idle surging between 500 and 900 rpm, no matter what gear is selected from Park to 1st.
Any help with this would be greatly appreciated.
