You should replace the thermostat. If you did that you likley replaced it with a high temperature thermostat. When hot, does the car run like its overheating? IE loss of power, poor acceleration, missing. If not, the former is probably the culprit. Make sure you get the Ford recommended temperature thermostat. Also, is the radiator clogged? Those should give you some ideas.
