    Tell me what the gauge is doing in more precise detail. Is there any issue with either the temp gauge or the oil pressure gauge when the fuel gauge becomes "fluctuating". Can you attach a code reader and see if you have any stored fault codes, P0460 maybe?

    the gas gauge moves up when theres not that much fuel & then it will move back down pretty much to where it was at first. All the other gauges seem to be working fine & no other codes
