Mine is and has been doing the same even after replacing both coolant sensors and unplugging the O2. My gas mileage has even gone as low as 9mpg on a highway trip this past weekend. I'm scratching my head as I sit here.

The normal spot for the temp needle is just to the left of the led while driving and lately it’s been about 2/3rds of the way to the LED.  I’ve been running rich lately too with diminished performance and lousy gas mileage around town (14mpg) but not sure if they are related.
