I had the same problem. Lights would slowly come on like they had to thaw out as I drove. The gas gauge did not work, drove with the odometer. Sent my dash, easy to unplug and pull out, to Mr. Whizard in North Dakota. Cost about $200 and works as good as new along with the gas gauge. http://www.mrwhizard.com/ Good luck. Don't know about the gas mileage. I get about 21.
