Hi folks,
My 2001 E53 4.4 is experiencing some acceleration hesitations at around 2000 rpm. The hesitation stops if I decelerate or accelerate. Moreover, there is no hesitation when I drive in sport mode, but we all know how much gas getting sucked in sport mode.

I have changed my spark plugs and check for oil leak. There was none.

I need help because this is really annoying.

Thanks
