We piloted the car at different speeds on the road and confirmed the truth. To this end, taken the following measures: First, check the low-voltage lines, inspection showed that low-voltage lines are normal. Second, check the electronic gasoline pump, found in the inspection, gasoline pump in the high-speed oil shortage. The petrol pump removed, the pump test bench
