Hay I’m the mim Escort. had already made a thread because of that but on which is somehow no longer answered so I do times en new. so had the problem already described and was told to replace once the KWELV (crank shaft ventilation valve) had also set pictures pure that my old broken or that of my mother. so have made a new clean and. Engine turned on a day later gin engine in the stand and without walking in again from, d irekt again turned on without trying to start again several times directly. then I noticed what when I drive in 1 gear he wires up and then I switch to the second so and then I wanted to turn up the time to see if he is still jerking. and that he still does a little and what I noticed is that he makes such a behavior at 4000 Ud as a seed of a front in the motor and brakes off the car or the speed and at full throttle he also does not pull through then he comes with half gas he feels as if he is pulling normally what he also does but as soon as full gas comes back it feels like one would have the speed brakes sometimes before 4000 turns or new at 4000. then if you have driven briefly with the car say times half an hour then I can turn the first, second, third up to the last passage to wave off. what can that be because can not be that now one part after the other is broken. Hope for your fast n answer because sir are already despairing.
