Your problem might have various causes. The car might not be getting enough
air, fuel or spark.
I've seen often a car which will stall when left at idle but runs ok when
you give it a little gas.
I think you should start with the essentials. How long has it been since the
follwoing were checked/replaced:
spark plugs
ignition cables
ditributor cap and rotor
air filter
fuel filter
etc?
