low power around 2000-2500 rpm??

I think that is the typical VANOS problem... do a search on this topic.

I agree. From what I've read, the VANOS activates (i.e. piston is energised) when the car is started (i.e. tick over) and and is de-activated at ~3000k rpm. So if your VANOS seals are not working, then it would feel like a power hole below ~3000k rpm. That's how mine feels anyway and I think I need to replace my seal.
