Fiat Fire Excessive fuel consumption

Hello, this 1.3 8v engine does not consume much, in this case it falls.
The engine was done a year ago, I thought that for the new engine consumption, maximum 10 lts per 100km. Now he went to 12 lts, ​​first I thought about the probe I already changed it, all new injectors, new butterfly body, new MAP sensor, new spark plugs, new coils, I thought the cylinder cover could be the problem, by the previous brushed, I got an ok and place it, it is really winning and tired, the last thing I have left is to check the computer, if there is a fault. I appreciate comments. greetings

Measure gas emissions .... Maybe it gives you a track .....

And the coolant sensor?

Hello, control the precion you have on the injectors ramp with Engine on idle must not exceed 2.5 bar to 2.8 with acceleration 3.0 to 3.2 bar greetings

Precion regulator Check it as the friend said above, ... and look at the data flow with scanner ... remember that any anomaly the computer compensates with injection ...
