minor changes lead to dead spot off zero throttle?

[Raux]

put the PCV on, and lighweight flywheel. valve job completed.

on zero throttle to about 5% there's a stuttering happening. seems a fueling issue.
didn't happen before the two changes even with the PCV's optimizer installed.

should I be looking at the PCV or a maybe an air leak intake/exhaust side?

While checking my work shop manual for other things, I noticed a remark about checking an air gap under a left side sensor connected to generator work. Absolutely no idea if that's relevant, but better to mention than not....
