S16 stuttering

[aggyj17]

Riiight I have been for a drive and I think I have sorted the stuttering but....... the car dosent seem like it wants to rev as smoothly/freely as it should. It just seems last like its taking forever to get to 6/7k whereas before it would rev right round no problem. I am 99.9% sure the avac system is working properly.

Any ideas??

Also when I was out on the test drive the bloody bolt holding the power steering pump has snapped so I gotta bloody sort that out now lol.
