Nic was doing a deal on £80 odd because of good exchange rates. only problem with it is that it takes at least 4 weeks.
i would do exactly as colsoop did. undo the 12mm bolts, top and bottom, 2 bolts, then unplug the air hose and pull the rubber fromthe inlet manifold. there is a little metal ring, looks like a trivial pursuit holder filled with orange segments, it comes out really easy. any trouble undo the top hose on the manifol and gently blow. the rubber sometimes gets bunged up with oil, as mine did, a bit of brake cleaner and TLC, be careful of the spring behind it, then put back together. (this is where i f**ked up originally, the ruuber must be flat side to the inlet and concave to the IAC unit).
then give her a try out!
