Question about 1991 Plymouth Acclaim
Car was taken 190 down a highway and then down a frozen gravel road where it bottomed out. Around 15 minutes down the gravel road the car started to stall. It still ran and got back to town, but now it's blowing black smoke out of the exhaust, it will only rev to 4 grand if you floor it, and while the engine is cold, I opened the cover on the radiator and it spat out a bunch of antifreeze.

Check your EATX relay in the fusebox.
EATX = Electronic Automatic Transaxle
the relay is for power supply to TCM (tranny control module) - 4speed will only work in limp mode (park, reverse, neutral, and 2nd gear only) if TCM is off. The relay controls the solenoid with allows fluid flow into the transmission.

Possibly the oxygen sensor. Had same problem with my Accord, had oxy sens replaced and that not only fixed the problem but I got better gas mileage after that.

If it works well at speed and acts up when slowing or stopped it doesn't sound like fuel filter or pump. You can try running injector cleaner through the engine to clean the carborator injectors or fuel injectors if you have those. Look at replacing the plugs and wires on the motor.

check for major vaccum leaks and it none found then you may have a bad idle air control valve, that controls the idle start there, good luck.

Fill the coolant & change the coolant sensor near the thermostat housing. The sensor is defective. This is a common problem with these engines. Do not overtorque the sensor. Max 14ft.lbs. Good luck!
