Bencina Hyunday Elantra Consumption 98

I happened to mention the problem is currently giving me 8k per liter, a year ago I changed oxygen sensor 9 months ago I made injectors to the sweep, I have changed spark plugs, air filter and benzine, however, the high continuous consumption, I have taken it to two scams and it has not been possible Of oxygen, he throws a voltage of 0.5, the MAP sensor threw at the beginning of 1 and when accelerating it reach 2.6. They told me that the MAP should be as a potential minimum of 1.5 and when doing it must reach 4, therefore apparently this sensor has a problem, my consultation is if there is another sensor that tea to change as the TPS, the temperature, the admission air, because I have read that they also consume bencina if they are bad, as I know if I need to change others and if the indicated parameters of the sensors that mention oxygen They merit a change to imply the expense of benzina, they told me that I should also carry out a cleaning of injectors with ultra sound, but the truth is that it does not seem necessary, I leave the aliestud if someone could guide me exactly not to make inecense expenses, thank you
