What about how the pin closer to the radiator on the temperature sensor is only reading 4 ohms which is way out of tolerance according to what it was said it should be. Could the idle control module think the engine is cold the entire time it is running and just be keeping the idle that high? Oh and by the way I did another check. I checked how much voltage the idle control valve is getting when the engine is at 1500 rpm and it is receiving about 4 volts.
