Another P1128 and p1130

Hello there everyone, I’ve been chasing this problem down endlessly and nothing seems to work, I’m truly at my wits end. I got these 2 codes, and here are the symptoms

Hunting idle

There seems to be a decrease in power, it feels like there’s more power on the table. Some days I start up the car and it feels fast, other days it feels slow.

Here’s what I have done to no avail to remedy the car

Replaced the AOS

Poured some Techron in

Cleaned the MAF

I’ve had the car smoked at a shop, and they didn’t find a vacuum leak.

My idle MAF reads about 10kg/hr with AC off, and here are the fuel trims

short term bank 1 and 2 bounce around from -.8 to 0 to 0.8

Long Term Bank 1 32%

Long Term Bank 2 30.5%

Can anyone make sense of this? Help would be greatly appreciated.
