How about enrichener solenoid

Do you mean the three way selenoid? we replaced it with new one

If it's not the float bowls, then I would look into your throttle position, as something seems off with it. You might need to re-calibrate it. Here is a video on how to do it https://www.rotax-owner.com/en/videos-topmenu/elearning-videos/481

OR you can look in the Rotax 914 Heavy Maintenance manual on how to calibrate and inspect it - https://www.rotax-owner.com/en/support-topmenu/engine-manuals#historical-documents

i will check it again, but if throttle position sensor is faulty, would it still send data to computer ? cause when i connect it to the pc i can see its movement properly and also i can calibrate it. checked both on tlr and buds. 

Does BUDS give you any information about faulty sensor? Sorry haven't used BUDS much.. and couldn't find any documentation about it. My TCU IS 741..

New update 

today i tried again , first the problem started at 4.000 rpm , then i reduced the power and re tried, now i get more than 5480 rpm with 39 manifold and after 2 second again the peoblem started. Here are the latest logs:

did I interpret it correctly, the servo drives the waste gate closed all the time. our 914 never closes more than 95% and gets full pressure. have you verified the free movement of the servo and wastegate on the ground by moving the throttle?
