sounds like it running fine on closed loop and then having a problem when the ECU takes over.
Most likely electrical/sensor issue of some description. Run a diagnostic and check for codes, as almost all sensor failures will generate one.
Also, please describe the way it runs hot...missing? backfire? smooth idle/but no power off idle? the better the description the easier to help
