Idles 10 sec then dies C6 Z06. New 100 mm TB makes it run lean, and idle stability is really a problem.
Symptom: Idles ok 8-12 sec then goes lean on the AFR > RPM drops way low > bounces way up (goes rich) and stabilizes for a while nicely. Then repeats itself.
Question: I was thinking to richen the AFR at lower idle speeds to beat it at it's own compensation. How to change AFR for idle?
UPDATE: 8/16/08. Idles perfectly if car is moving over 2 mph out of gear. Reproducable only at 0 mph This is not an MAF calibration problem. It is some other table. What?

Everything is running perfectly AFR-wise, so there is no indication to change the MAF. I should have been clearer.
HOWEVER, I was going to try to raise it a little on the bottom part to enrichen it at low gm/cyl. That's the only thing I can think of to enrichen it (if that would work anyway.)

Again for those trying to help. Please note:
UPDATE: 8/16/08. Idles perfectly if car is moving over 2 mph out of gear. Reproducable only at 0 mph This is not an MAF calibration problem. It is some other table. What table would do this.
