My truck is the first time that I've ever used a WB sensor.
At idle and part throttle the AFR seems to vary wildly. Is
this normal, perhaps due to the narrow band o2 sensors?
(For instance at idle my truck's AFR is roughly mid 15s but
can bounce between 14s and 16s while I'm sitting idle.)
Should my idle AFR be lower? Should the AFR be stable?
My truck had stock 23# injectors, but now I'm running 60#.
It has a bog off idle which I'm led to believe is because I'm
running the 23# inj offset values and the 60# injectors likely
need more time to open/close.
So I'm starting to slowly increase the inj offsets to see what
happens to driveability. Can I expect any change in the part
throttle AFR values, or are they simply what they are?
