Well I was wondering if this would happen and it did, I got a PO128 this morning, thermostat slow to reach operating temp. I have a modified stat and a supercooler, anybody else had this code? It's only been in the 40's here over night so far, as long as I know what it is I can deal with it I guess, I'm sure it will be more frequent in the middle of winter. I cleared it and it hasn't came back the last 2 nights, which have only been in the 50's.
Sounds like we have the same set up and the same morning temps. No issues at this end (yet).
You should have gotten one of those cool tighed1 supercoolers. No problem here!

I have the TVT drilled out thermostat in mine still and if it gets below 50 deg outside I will throw a code. It's not really a big deal since I have the capability of clearing it......
I installed the PTE over the summer. I have gotten the same CEL code several times over the last 2 weeks. If it is below 60 outside I get a CEL.
I sent Patrick an email to see if he had any thoughts on it, but I haven't been able to check my emails at home or work this week. I should be able to this evening. I will report back what he says. If it keeps it up I am going to put the OEM T-Stat back in until the summer. Bit of a PITA....
Edit: I just had an opportunity to check my email. Sure enough Patrick from PTE had responded. This guy really stands behind his product(s).
I am going to try driving it without the a/c or heat turned on until it warms up to see what impact that has on it. Patrick recommended that I give that a try. It makes sense - I should have thought of it to give it a try.
If this doesn't work, he has offered to exchange the one I have. Again, great guy, pleasure doing business with him.
I will report back when the temps drop again and I am in the car.
Cheers,
