hi there

i have a problem with my car.
if i go soft on the trothle its fine but if i press it to the bottom the car starts to fail betwen 0 and 3000 rpm. then if i shut it down and restart it its fine. did anybody had a similar problem?
i already replaced the fuel pump the compressor  the blue sensor the black one the one that is on the exaust and a few other things. i am tired of going from shop to shop....
please mind explanations cause im from portual, make them simple.

i solved the problem, it was the knock sensor that was not in the best of conditions.
i replaced it and its fine now.
