Failed etest :(

alright guys well heres my problem. I went for an etest last night expecting to pass pretty well since i installed a brand new O2 sensor and had no more check engine light. but i noticed after the O2 sensor i have a decrease in power .

so what i failed(so the guy said) even though the sheet says (valid) next to the numbers on was Dilution Percent, it was supposed to be no higher than 6... mines at 14.06 at 2500 RPM and on idle its at 13.61 . i also failed on HC(ppm) whatever that is, the limit for that one is 200 and at 2500 rmp i got 67 so that passed but at idle i got 448! Captaine34 told me how to fix that. SO what i think the problem is is my CATs , i was driving for a while with a broken O2 sensor and i read on bmwe34.net that could have made carbon diposits in the CATs . so before i replace the CATs or make whole new exhaust i just want your guys opinion because im sure theres a few people who understand these numbers more than i do or have had the same problems Thanks in advance
