Ford Fiesta RS Turbo.Fallo Motor Da Saltos

I have a RS Turbo Ford and a failure has left the engine suddenly, I explain it: when walking goes perfect, but when the turbo begins to put the car the car begins to jump as if it took his foot from the accelerated and accelerated again suddenly, he only does it when the turbo begins to blow if I carry it without the turbo worse does not fail. I close contact and start again it is removed but it comes out again, I have tried everything and I have changed pieces of another car that I have the same does not fail and I do not take it away.

Well, although the post is a lot of time ago, I will answer the same.
What happens to you is because you have the turbo "blowing" at excessive pressure. The Turbo party comes with a serial pressure between 0.5 and 0.55 (0.6) bars. Having excess blossomed, the MAP (Manifeold Air Pressure) probe, detects an excess air pressure in the intake manifold (surely that turbo was blowing more than 0.8 bars, which I think is what the MAP comes to) and the switchboard enters "safe" mode and begins to cut injection as engine protection. You have to be careful with these things because having the turbo blowing the beast, you are chopped with connecting rod (the explosion in the cylinder occurs when the piston is still in the ascending race towards the PMS). You load the engine in less of anything.
