First check for any vacuum leaks, ie bad lines, intake gaskets, pcvvalve, then clean the throttle body and the ISC unit, if that doesn't fix it then you will have to get the codes checked for further diagnosis.

If all of your vacuum hoses check good then your only option is to get the codes ran, but you need to find a shop that has the equipment to check the old Ford OBD 1.

I had same problem but I changed the TPS unit (throttle Position Sensor) and now runs fine.
