What was replaced in the tune up? Usually the coil paks cause these types of issues. Also fuel filter or fuel pump will allow enough fuel to start and sputter like you describe.

bad plugs + wires and coil.also weak fuel pump.stopped up fuel filter and fuel injectors.

use a stronger spring,have a look under dash and you will see the accelerator pedal has a return spring,either shorten it for more resistance(heavier feel) or replace it,easy to fix,you can even put a little return spring at the throttle end on the engine if youre careful it doesnt foul anything

these cars are carburated motors and need around 10 minutes to warm up because they operate at higher temperatures.

Sounds like the IAC valve is carboned up. This valve can usually be removed easily with 1 connector and 2 bolts. It is how the engine controls the idle speed. Many times a can of carb cleaner and working the piston back and forth on it will free it up for many more miles.
Turn on the a/c at idle. does the idle speed change?
