Ok. I have an 83ZX with a digital dash temp guage. About a week ago, it was kinda cold and rainy out. I let it idle for about 10 minutes. No lights on the temp guage. I drove out of town about 3 miles at about 60 MPH before one light on the guage lit up. At about 12 miles from home I had 2 lights lit on the guage. 3 lights at about 40 miles or so. Does this seem to be running too cold?
