replace my thermostat? Would a stuck thermostat just keep my engine that cool in 80 degree weather?

I would swap another ECT sensor in there and see what happens.

Default Not necessarily. I replaced my old one with one from PureMS and it was fine for a few weeks. Then

all of a sudden my readings started dropping lower and lower and I thought "crap!" my t-stat is gone.

Now, granted, my old ECT sensor wasn't bad, so I swapped it back in and viola! everything was back to normal again.

Def try a new ECT sensor before anything else.

Oh, and I didn't have any codes.

See my response to you below. They don't always last long. Mine lasted <1k miles.

Default Just did mine...

Not sure this helps, but I had the same symptom (little to no indication on the coolant temp. gauge). Since replacing the OE ECT sensor with a green one and replacing the thermostat (as part of a t-belt job), the gauge works as expected.

Replacing the sensor seems to have resolved some cold-start issues too.

BTW, ECT = Engine Coolant Temperature
