Just got my new-to-me 1991 red/ivory NSX up and running after replacing the ALB accumulator and front struts. I absolutely love this NSX! Well, the temperature here in north-central Texas finally cooled down below 50 degrees F and during my 20-mile trip to work this morning, I never saw the water temp gauge move off the peg. On the drive home, the CEL illuminated with the OAT around 60 degrees F with the temp gauge still on the peg. The temp gauge registered up to two bars at a red light, then returned back to the peg at highway speeds. The CEL light does not illuminate after it sits off for a while when started back up. Am I missing anything other than a failed-open thermostat?
