Ford Focus 2001 Intermittent Failure

How about friends, I hope someone can advise me with this problem I have with this car.

SYMPTOM: The car works correctly in Readi (in low) and if we do it little by little it does not have problems, but by accelerating it faster the engine tends to go out and this causes it to lose the Fueza, the engine.

The following was reviewed:
1- Compression of the pistons, is within the specifications.
2- It does not present fault codes in the ECU
3- The owner of the car had already changed the gasoline bomda, currently has 40psi
4- Check the MAF sensor (voltage) and apparently it is working properly.

Friends, give me a track, since I am about to throw in the towel, greetings and thanks in advance for your time

Possibly your problem is that when rapid accelerating among too much gasoline in the cylinders, check injectors can remain open.

How do you look as the talks is the MAF ... it marks you well but usually in that car is the problem you have .... look to know better disconnect it with the car on and do not let it go out and thus handle it and you will realize ..... If you feel it better you change it is very common that fault ...
