Default idle is driving me f*cking crazy!

well ever since i did my swap and tune my car has its good days and it has its bad days. lately its been alot of bad days.
sitting at idle it goes up and down until it stalls. i thought it was a bad iac valve so i replaced it...no good, check all vaccum lines..all good, even cleaned my maf and even swapped it with a dif one and it was still doing it. before i sink more money into this ****ing thing i need some opinions. and the cpu is not throwing any codes.

give it a ocuple days to see if it breaks in and gets better... thats the only help i can provide on this situation. cuz i was pissed when i replaced mine and it did the same stuttering, but then a couple days later it smoothed out.

i just remembered that a month or so ago i threw a code for one of my o2 sensors but i cleared it and it never came back, and i remeber my tuner mentioning something about one of my o2s, u think that could have something to do with it?
