This could mean that also your AOS is on a way out - somebody more knowledgable could chime in on that.
Thanks for input, I guess it cannot hurt to change the AOS, just more work..

Update:

Switched AOS, MAF, o2-sensors & spark plugs, still no luck.. Then I put back the oem cats, instead of the cheap eBay ones. o2 and HC back on zero again!

Anyone else had bad luck with eBay cats?

I had similar issues with 200 CPI cats. On this thread at the answer #2 is the reasons for the issues and how the MOT was cleared.

Hmmmm... So heat.. extreme heat? What about if I put exhaust wrap all the way over the cats? I have wrapped the headers, maybe try to wrap the cats to. Anyone tried that?
