Not really a problem but an experience. Was filling up the tank with the ignition switch on ACC, when I finished filling the tank, I started the truck and the guage read 1/4 tank. I turned around about to go off on the gas station manager. I tried putting more gas in it before I sued them for inacurrate gas pumps, but found out it really was full. I drove off and over the next 20 minutes, the guage and the computer readjusted itself to full. Wierd. Anyone else experience this? I suppose keeping the ignition on with the cap off tricks the computer in some way.
