I have 2000 hyundai accent, delux model. For the last 10 months the engine cuts out at lights, or when I slow down, or go around a corner - this only happens when the fuel tank is full. After going 90-100km it no longer happens. If I just dont fill the tank full its ok, but this isn't good enough. The service people changed some fuel sensor, that didn't work, now they say its dirty fuel, how can it be? it would happen all the time, and its done this snuffing on a full tank for 10 months.
