So lets try this again ask us your questions because I didn't see a question in your first post just a few statements about having a CEL with no code, a bad thermostat and a ticking noise. So it seems you know you have a bad thermostat so fix it and that should take care of the temperature fluctuations and then get us a code for the CEL I suspect it is telling you that you have a bad thermostat.
