Code P0128 means engine is not reaching normal operating temperature. That could mean low coolant, faulty/incorrect signal from sensor, or coolant thermostat stuck open. When you replaced the thermostat, did it look weak or stuck open? If it now overheats, you may have installed the new thermostat backwards. It's real easy to do. Also, did codes P0128 reappear after you cleared the code? If "no" then the problem was the thermostat. But overheating might mean it's installed wrong or there's air in the system.
