ok guys... this started just about a week ago...
whenever i drive, most of the time my wideband would show 10.0 anywhere before 1600 rpm then after i pass that, it goes to normal.
Problem is, its that anywhere under that, car will bog like crazy but right after passing 1600rpm, like i said, car starts to drive normal again.....

On idle, im fine because it reads 14.5-15.0. so this only happens when i drive normal on first and sometimes on second gear if i shift early on first ... any ideas why i would be running so dang rich?

 

Are your O2 sensors hooked up and working (i.e no codes for them)? Mine is the same, though not as rich. And it is due to the fact that I do not have any primary o2 sensors. In the case of the fed spec VQ eqipped Maxima (A32/A33), it may go even more rich since they only have one set of o2 sensors (vs A33B being all Cali)

What's your fuel set-up like?
AFPR?
PSI?
Which Injectors?
