Your car is a 96 and I have a 99 so possibly they are different. On the 99, the shifter cable goes to a lever on the transmission. It is attached by a bolt and nut. You might check if that has come loose some how or if the cable is broken. There should be another cable from the shifter to the steering column which has to do with an ignition interlock that only lets the car start in park. The cables at the throttle should go to the throttle body and cruise control and probably have nothing to do with this problem.
