Get a can of throttle body cleaner, start the engine and when the engine is idling, spray the cleaner at all the vacuum hose connections and see if the engines starts to rev up a bit. If it does, you have a vacuum leak at that point. Keep checking you may have a few. If you have enough vacuum leaks your car can idle but as soon as you put it under load, the increased air throws the fuel mixture off and with too much air and not enough fuel the engine stumbles and dies.

What would be wrong if the fourth gear doesn't work in 1996 z24 but all the other gears work fine?

If it will not go into gear, but the other gears work fine it would be the synchros and if it looks like it is in 4th gear and feels like it is in 4th gear then it could be that the gear selector is not aligned properly and the car is not in gear although it looks like it is. Also, if it looks to be in gear and doesn't work and the motor just revs freely, then all of the teeth on the gear itself could be work off.
