07' 28k miles. Stock with just a straight pipe in place of the cat. Spacer added for the O2 sensor so I don't throw a CEL.

Recently my car has been running insane rich. Park the car and go inside and smell it in the bedroom if the window is open. So far I haven't noticed any loss of MPG. Is this due to the O2 sensor isn't giving a 100% correct reading so in turn its adding more fuel?

Or is it time for a AP?!

 

yup you need an AP...get used to it, its gonna smell like sh*t, ive been running catless for a couple of months now, but im used to it

 

i have the ap and it still smells like dump

 

Figured with the AP I could just lean out the mixture a bit. Oh well. I guess ill just leave it be.
