Here's someone today that reported they 'hollowed out' the cats. Wow.

Does that actually accomplish anything useful?

The code im getting is for the ICV so I cleaned it and I still got the same situation, the ICV code comes back... How can I tell when the ICV needs replacing and is the ICV even the problem? I dont have idling problems which seem to be due to a bad ICV...

Ive also hollowed out the cats, changed the plugs and did the valve cover gaskets trying to rid my car of this poltergiest... I just want some feedback before I go and spend more $$$...

Thanks in advance for any help and advice!
