My quandry still exists. The gauge does move as the jeep warms up. Sometimes the jeep will ramp up to 200 deg F on the gauge. As soon as the jeep moves it is back at 160 deg F. I wish there was a way I could confirm we were in open or closed loop. I wish it would flash a code or something.
I have done so much with so little for so long, I can do anything with nothing forever.
