I have a 2001 Chev Silverado that the oil gauge does some flickering. it will be at 40 then go to 50 and back again. I have had this for a year now. could this be the oil pressure sensor? if so where is it on the engine. Also just lately my fuel gauge is doing the same thing jumping around. Is this a ground problem maybe? then I would think it would be on all 4 gauges. Let me know what you think
thanks
