I was driving yesterday and she started to have a little hesitation and when it was idling and i rev it up and she stumbles. And the light came on and i read the code and its P0462 Fuel Level Sensor Circuit Low Input. The car has 7.5k on it since I changed everything over so why now? And what is the problem one of the FPDM went bad? fuse blow on the Dual FPDM Wire Harness?
