Tfsi power loss

[walterwaste]

My 2.0 tfsi loses power when going over 3k rpm, it is like i'm lifting of the throttle. When scanning for codes i get P12A2 and P0304. I did have a check engine light for a couple of days then it vanished but the problem was still there. Does anyone have a clue what the issue can be?

P0304 is misfire on cylinder 4 

P12A2 is fuel rail pressure sensor inappropriately high.

Hi there did you find the problem I have same problem but with PO302 it could be my injector I think.
