Which Temperature Sensor did you replace? There is the block temperature sending unit and, under the third intake runner, an Engine Coolant Sensor. The last is the one that the ECU reads to determine the fuel mix for cold start running. Unles something has failed in the ECU, changing a bad ECT Sensor has to affect the ECU output.
