I installed a Nordsc(sp?) A/F meter and tapped into my pre cat O2 sensor. It sways from lean to rich very sporadicly(sp?) at idle and partial throttle. Under WOT with Bernds IAT in the off position it nails the rich line, I'm sure this is the 24# injectors, the PCM programmed for a SC thats not on yet.
I guess my question is, is it normal to sway from lean to rich so easily. I goes haywire, back and forth, back and forth.
With the IAT on and leaned out to the 7:00 position (190 degree's)the A/F will lean out, then it's like the PCM overides and compensates for it and I'm right back in the rich position.
I know that the SC will help by getting more air into the system for that extra fuel but I guess I want to be able to adjust it now or is this just now possible with the 24# injectors and the PCM in it's current state?
Thanks,
Shawn
