so i had a post here before bout my rear o2s, i did alot of research and alot of ppl had this prob, not only audis, but no one post the solutiin to it, and these are my rear after cats, on a 99 2.8 v6. quatroo,

i recheck the connections they are clean and snapped back on as they should. i am confused as what to do now? since i have to pass inspection asap.

please help. needa get this done before the 28th
inspection here in mass, and way over due already

ok so here are my codes exactly.

17606 or p1198 not active
17607 or p1199 not active,

16524 or p0140
16544 or p0160

and another one non related
p0411
(secondary air injection)

my before cat redings jump up and down if i rev and even while idling which is normal(the front ones are active and working properly)
my after cats reading just sit at .425 both of them
same exact as when before i hooked up the new sensors???
i rechecked connectors snapped em back on fine, no problems visible there
alot of other ppl seem to have had this and always wiring prob, i can not find a solution yet,
and could this be a fuse? if so where am i looking for one?
