I need you help guys in engibe hesitation

Hi guys i'm really depressed because of my e46 318i m43 engine 1.9L

I'm suffering from engine hesitation since i bought the car.
I have 97k kilometers on the clock
Since it was 30k kilometers I'm suffering from engine hesitation between 2000 and 3500 rpm

I replaced so far the following
Fuel pump vdo
Spark plus
Fuel filter

There is no codes and all sensors running great
