Adjusting CO in fuel head

Hi Guys-
My car is a 964 Turbo. Trying to get baseline CO adjustment dialed in before I do any adjustments on my BL adjustable WUR (which I don't think will require much - maybe just WOT boost - we'll see) but anyway I've been trying to get warm/hot idle at ~13.5 on my AFR meter. So I will get it there and it will be consistent for a couple days - then suddenly it will be 14.5 for a few drives. Then yesterday after things seeming to be pretty dialed in for a few days I get in the car to go home (after driving the car a few times during the day) and is idles really low at startup, AFR is 15-16+ - it gradually came down as the engine came up fully to operating temp but never back to 13.5 (more like to about 14.5 maybe 15. And exhaust popping on decel _seems_ to have increased, but that could just be me. Air pump has been disconnected for a week or so while attempting to get things dialed in.

Any thoughts appreciated-thanks
