Hello again after a full engine rebuilt the problem is still there
The car has also new lambda sensor, crank sensor, spark plugs, leads, fuel pump, fuel filter, coils.
There was one time i start the car before engine rebuilt and all worked fine, idles perfect even cold and i think i dont know why the brakes seem more responsive in light brake pedal touch.

Any ideas? Is there anything else to change?
