After bringing my FJ back from its 10+ year slumber I have found all the gauges work, but the fuel and temp gauges fluctuate. They come and go in unison and randomly. It only affects the temp and fuel gauges.....the oil and amp gauges never have issues. I'm guessing its a ground issue but does anyone have a suggestion on where to look first? I've done some searching but can't find anything regarding this exact issue. Is there a certain location that would only affect those two gauges? I've wiggled wires under the dash it hopes that I would catch something but nothing yet. They just randomly work and stop working as I'm driving down the road.
Any help or advice would be greatly appreciated. Thanks.
