Problems with my Ford Focus

Hello everyone, I am new here but I have seen how interesting your comments are. I request your help, I have a Ford Focus 2001 Motor Zetec 2.0 and currently has the problem that when I go going it starts to pull as if it runs out of fuel and goes out, I turn it off and after a few minutes I start it again and as if nothing starts well and continues its march.

Before I did it in long tours and when I began to give jalones I stopped accelerating and the problem was removed and the car continued its march but now it has worsened as indicated above.

Added to this I have the problem that velocimeter does not work (aspiometer), stop working after changing the clutch system and the mechanic did not realize and short the cable that goes to the box and I do not know where and how to connect it, someone can tell me and send me a diagramite.

Thanks for all the answers you send me.

Greetings,

1 PASSE Verify if it has a combutible, when the engine is stopped and the most motor place. The signer of the rabage must have a guarantee for the work done, as is the guarantee, 2paso you are talking about two or more chau cables

Check the possibly defective motor turning sensor and contokilometers cable such as independent cables or one coaxial type.-

Go to the workshop and check you the accelerator pedal potentiometer
