There should be a solenoid on the throttle body that kicks the throttle open when the a/c is turned on to keep RPM's up.That solenoid might be faulty or the wiring going to it.Possibly the switch for the a/c also, but check the other things first.

Where can I find a Ford Windsor 302 for a 1985 Crown Victoria LTD Coupe?

You can order a remanufactured engine from any NAPA or Carquest auto parts store (my 1st choice for quality), there are many other sources including Autozone, Advance auto parts and many more. Expect to pay about $1800.00+rebuildable core charge.
