I just fixed a vacuum leak in my car and the o2 sensor reading went from a steady .1 volts to .40 volts or so. But it still seemed a little lean and wasnt really cycling.

I am wondering if I missed a turn when screwing with my FPR and did not turn it back to where it originally was. When I did put it back to [what I thought was] the original position, the A/F meter stayed at 14.9 at idle. When I turned it some more the a/f meter started cycling back and forth over the 14.7 mark every second exactly how it should. But i'm not certain if I have it at the right pressure.

Is there any way to check the adjustment with a narrow band A/F meter or EGT or with the o2 sensor? The car has custom software so I'm not sure if the software was written at stock pressure or at another pressure.

Huh? I'm more afraid of it being too lean/predetonating

um if its at idle you have nothing to be worried about at all
