Ahhh balls!! I cleaned my ICV out but no good for me. I've gone down the extent of buying a new fmic now as mines bashed about so not sure it's it's leaking. The ICV is easy to get to and clean. It's right on the end of the inlet left side. Held in by two small 10mm bolts and some earth leads attatched the right side bolt. Take it off and pry the tabs over a little and remove the insides. Be carful it doesn't all fall out when your doing it.
