fueling

[Jama665]

Im confused as to where all my fuel is going. It seems massively un economical at the moment and seem to be getting half the return im used to. 20quid roughly returning 40miles. Its almost like theres a fuel leak but I cant smell fuel anywhere. What could be effecting my fueling so badly.
Its a 1.8t avj

the auto choke will be on longer and will take a lot longer to warm up

Ok but its not that cold and id had the car more than 1 winter so cant be that.

But I know the temp sensor on the bottom rqd hose is faulty. Although im unsure of its use. I know the temp sensor on the back of the cyclinder head is used by the ecu. But not sure what the bottom temp sensor relates to anyone know.
