In my EFI 22re 4Runner I just went to get it emissioned and failed terribly! On the C0 level it's supposed to be max 2.22 and was 7.52! What is causing it? O2 sensor? Leak in exhaust making computer go wild? On a side note my HC is supposed to max at 316 and is 151! Doesn't that mean I'm burining a ton more gas than I should? I don't know how these readings work and what to do to solve them...
