Just an update. I have replaced camshaft position sensor (intake) and maf. No more error codes.
However, despite having no errors car behaves weirdly.
When I try to lets say join the traffic (so quickly accelerate), it seems like it doesn't want to accelerate, its is very sluggish. Almost caused an accident couple of times already trying to join a busy traffic when my car wouldn't accelerate until raves got higher (around 2k rpm). It only happens sometimes.
I though that camshaft position sensor replacement would fix this issue. Is there anything else I should look at?
