I need urgent help

Hello, thank you all for your advice, I am the boy of the Hyundai Elantra 2000, they reviewed what you told me and is fine, it has been removed a little, now it is that when it is half a tank or more of gasoline you are accelerating and you lift a little your foot feels like it will be stood and turned off, but if you are less than half a tank, it does not really give me problems, this car is really a fortune. head. Help me for FA .. [IMG/]

It is easy what you say the whole problem should be the pump, because you have half pond and work well and with more, it does not make much sense, to blame another cononent, to check again but well done you want the pump to overheat or drown check it

hello.
It seems that the situation is complicated. But it is very close to the cause that Kikemec says. But we could make sure more hopefully measure the pressure pressure in the injection manifold in the conditions that the failure occurs to determine whether it is a product of a pressure loss or an over pressure. I hope you can. To be safer.
luck...

Hey already checked that the gas pump is not clogged?
Czech the injectors, the distributor, the synchronizer.
It is probably a merely electric problem, I just had a similar problem with a golf a jetta and an atos.
One changed the gasoline pump, to another the computer, and the last one was the carburada, Czech what I tell you in that order and you will surely find the fault. Sometimes if the motorcycle maker is not well connected or its terminals are broken the RPM and the vehicle is azon. Wash your gas tank.

Have you looked at the breathlessness and the canister of the canister ????

That it is not the first time that a deposit takes pressure to have the stuck canister and begins to give a lot of problems.

Look also the canister's solenoid valve although if it fails, a fault code appears in the switchboard.

All the best.
