I went about 100 miles and the CEL came on with the same Code P0128.Bleed the system reset the code and about 175 mile later the CEL came on with the same code. No other code but P0128 shows. Anyone have any idea what the issue is

Therm. is being held open causing the engine to not heat up to a full 190 degrees. make sure you put in a 190 degree therm. and unhook the negative battery cable for at least 5 minutes to clear the code. the system could need a flush too, with over 100,000 miles or 5 years
