Re: Running cold
Possible the ECM needs a re-flash for that problem. I looked at all the service bulletins I could find for all years of ZX2 last week thinking I might find something out for you, but there was no mention of that problem.
My '94 Impala SS would get hot in traffic when I first got it, and after bleeding the system and installing a new stat with no improvement, I called a dealer and they said it was common on the LT-1 engines since the water pump is cam-driven and turns slow at idle, coupled with an unrealistic set temp for the ECM to turn on the fan. So they flashed it to lower fan set temp by 15 degrees, and it was fine after.
Sounds like your problem might be similar, even if opposite.
