You sure have thrown enough money at it. Older cars are harder to diagnose, but my first thought would have been the throttle position sensor. It tells the system that you hit the gas and if it is not sending its signal, then when you hit the pedal, a lot of air will go in and the system will not inject more fuel. This means that you will get either a weak combustion or no combustion at all and the engine will stall.
