Usually a problem with a dirty throttle body or a faulty idle air control valve. The computer controls idle speed by regulating how much air enters the intake thru the valve.

Have you checked the cam sensor? Also does that vehicle have a "throttle position sensor"? Some cars use both MAP and MAF sensors, not sure about your particular vehicle but if it is one of those, cleaning the MAF wouldn't hurt. Good luck.

2. Loose, corroded or broken battery cable.
3. Alternator not charging or below normal rates.
4. Failed ignition coil, ignition/electronic module.
5. Failed CKP, CPS, CMP, MAP, TPS, or BAS sensor.
6. Faulty ignition switch.
7. Water or dirt in fuel system, carburetor or filter.
8. Fuel tank vent system plugged or gas cap not venting.
9. Fuel tank empty.

85 Citation stalls at idle after reaching operating temp

Are you sure this has a carburetor? By 85 most were fuel injected. Did you check the gap on the plugs? Clean the threads and seat? Map sensor maybe bad.

the very 1st thing for you to do is have the OBD 2 electronic engine control system tested for trouble codes, whenever you have a stall like this there is almost always a code that is stored for the problem, which in your case will most likely be a crankshaft position sensor, but do the test.
