High fuel consumption

Hello, Loidee! My Elenore's making probs again! Not only that the fuel consumption is high( According to BC I come with a tank filling only 320 km, and that's true too) but if I stand out a little more gas you have the feeling, as if the sweets swallowed at the beginning, before they start driving!Speed fluctuations in the stand however I do not have!!! Is it still the Lambda probe or what can it be?Greetings of the Hamburger Marc
