common thing with these-there is a mod from ford, if you can find a friendly partsman at your local dealer,he will supply you with what you need.
a quick fix is to disconnect the speed sensor(follow the 2 wires from the speedo cable at the gearbox to the bulkhead just right of the air box,
there is a connector there,undoe it,and try your car.
if all is back to normal,and no stalling,leave it as it is-no harm will be done and you can continue like this till you sell/scrap the car.

Try cleaning fuse no. 32 (3 amp). Worked for me.
