I think it's fair to say that I found the source of low temps...
Put in a new thermostat in place of this thermostat frame. Refilled with water, and it got up to temps no problem. It's been running for the past hour at idle, temps never got above 185°F. Great success.
Replaced the air filter while I was at it.
Looks like something going on with the O2 sensors still. Full disclosure: I'm just a shadetree parts changer. NOT a mechanic. So I just pulled up everything that was related to oxygen sensors: long/short term trims, voltages, etc. Can't 100% interpret what all these stats are, but just looking for something to stand out. Looks like at least one is not behaving like the rest. (Any tips on correct interpretation of all this would be greatly appreciated.)
Another screenshot:
On the bright side: after over an hour of running at idle there are no CELs yet. I guess all of those CELs earlier were caused by absense of a thermostat? A few are likely to pop up though once I take it for a drive. Hoping for the best, but expecting the worst. For now I enjoy this no CEL screen
We'll see what the test drive brings. For now I have new oxygen sensors ready to go in, once the current ones give up and stop fighting me. Also new-to-me steering rack is ready to replace the current one, since the one in the GS is leaking badly and inner tie rod is nearly separated. Interesting how the inner tie rod that separated is on the driver's side, but it causes the passenger side wheel to have quite a bit of negative camber... Nothing else in suspension seems to be a suspect, but I can tell the steering rack has been replaced before. So likely improper installation by previous owner?
