so, i got a smog check
and faild, 92 v6 auto

my hc at idle and 2500rpm were about the same at 2200, legal is 220,
my cat clogged about a month ago so i just cleaned out the honey comb stuff,

my check engine light is on too running lean and getting about 13mpg, with 32 and 4.88 stock gears, i was getting 15mpg city after i replaced alot of stuff after my sister blew the head gasket, about 3 months ago.

for the lean a\f ratio, i replaced the o2 sensor with an oem replacment, denso one, didnt change anything,

any sugestions?
