Then all the while I was at the light, it stayed there, but once I started moving again, it went down again. Then when I reached home and parked, it went up again.
I have replaced the fans and ECT, so don't go that route. I thought about air in the system too, but there isn't. I've flushed the radiator twice and changed the t-stat twice after this problem started. I've changed the radiator cap as well.
Someone did mention that it might just be the gauge itself. Somewhere else I read, the ECT has a wire running from it to the ECU and that wire might need changing. Did yours start happening after your t-belt/water pump replacement?
Are your gauge readings similar to the pictures I had posted?
