i had the same problem with my 93, what degree thermostat did you put in? i think factory specs are 195* are you experiencing overcooling? if so you could try a higher degree thermostat. (either 180* or 195* dont run 160* for daily driving) maybe a electrical problem too try replacing sending units (one on heater hoses other mounted on intake somewhere)
