I just changed all 8 injectors and 8 coils ( USD 2500 yay ), plugs are 8000kms old, I get less jerkiness but I can stil reproduce the issue
. One symptom that I didn't had before is missfires, mainly on 5,6,7,8 + one or more from [1..4]
Next step is replacing the plugs, then checking wiring harness then trying another ECU ( maybe a coil driver issue ).
