Also when flashing stock calibration - its in the state to receive a cabcontroller information which is supposed to be saved before any ECM-related "adventures". I am guessing people tweak it to make ECM think that it is freezing outside, so "magic valve" would stay closed during engine operation. Also if that sensor is disconnected, program will guess and rely on other data and use "constants", so even if sensor is disconnected, it will run fine. But again, may be sensor itself is providing messed up data. Those things cant be answered 100% accurate by forum members guessings.

everything you describe there screams 'bad delete!'.
