Hello everyone
The fuel pump, oxygen sensors, catalyst changed after my 307 1.6 xt premium automatic car was put in the wrong fuel last September. The last brain has been reset, but there is a problem in the vehicle that nobody can solve, actually it is not a big thing, but as time goes by, it gets stuck in my head and my nervousness deteriorates.
Normally all of us trip computers show almost the same values. But my 307 was a bit confused after this incident. Instant fuel consumption shows 9-10 lt / km on a straight road while driving at 90 la. This rate goes up to 15 when I reach a slight slope. However, the fuel consumption of the vehicle is not the values written on the normal screen. In the past, when driving to 90 la, instant fuel consumption of up to 5 liters, whatever I do, does not fall below 8.5. The car slows down when I fix it at 8.5. I have read a few things about how the oxygen sensor transmits these values. We changed but the problem is the same. What do you think is the problem? I am waiting for your suggestions. Thanks everyone already.
