Hello, I have a question regarding my Audi 80, 2.0, 90 hp, BJ 6/92: Oddly enough, I can only dose the gas supply very imprecisely. Especially in the first two gears it happens that the car is jerking at constant accelerator position. Also the acceleration does not work smoothly, but only very unevenly. In idle mode, turning up works impeccable, however, if gears are inserted it seems as if the fuel supply is not constant. I don’t really know, so I’d love your help. My considerations are absolutely theoretical in nature. 1. Gas train jams somewhere / doesn’t fit properly in the lead. 2. Gas filter partially clogged (the dealer obviously emptied the petrol tank before sale, so there might be particles lying on the tank floor in the filter) 3. Lambda probe sporadically defective –> Air Gas Gemi 4. Problems with the air supply. 5. Throttle valve opens / closes not correctly. 6. Gasoline pump does not work properly. 7. Problems with combustion (Zündverteiler, Zündkerzen…) I would be very grateful if you tell me what this could be and how I can fix the error. Sometimes it is very annoying, especially when climbing under load the error occurs. Thank you for your answer! LG pjotr1987
