Bleeding went good today! Had no more airbubbles after 15 minutes of bleeding

. Jacking up the front of the car a little bit and squeezing the tubes helped a lot. But guess what: i still got the same problem

. So it's time for a recap. In my first post i wrote that the car would stall after two minutes which isn't right. After some more testdrives i discovered that the car rev's up good as long as i keep it under 3000-3500 rpm. When i go over it the engine starts to stutter. Max. throttle would lead to stalling or sometimes it would go up to the redline but eventually the revs would fall down again. Things i checked so far: airflow meter ok, throttle position sensor ok, water temp sensor ok, cam sensor ok and crank sensor ok. Injectors are refurbished and tested. I cleared up the mess under the intake and throttle body heating is gone. So i've got new vac hoses and gaskets. Also my intake boot is in good shape. So it is definitely not air leaks. But today i noticed when the lower flap from the throttle body is actuated by the upper flap, the engine is at it's critical point to stutter. Maybe this means something?
