I have been trying to balance the AFRs on my car using a wideband gauge and after hours and days of testing in the 14s on idle and cruise I have found that my car does not like being in the 14s and idles much more smoothly in the very low 13s.

I would rather run in the 14s however it just doesnt idle smooth at all. I have had to remove the wideband meter and just tune maually to get it smooth.

Is idling in the low 13s and running high 13s/14 just the nature of CIS or does it sound like a hose leak or other issue? Also I have a msd 6al installed. Could plug gap help or hinder as I have tried standard gap vs larger gap and see no difference in the richness it needs to be smooth.
