Need help with low idle issue

[03protege5]

All, maybe someone can help. I have 03 p5 with 160k. MP3 ecu swap with about 500 miles since the change. New MAF sensor and air control temp sensor. I’m still experiencing a low idle while stopped, it drops to about 200 then will bounce back up to maybe 700 and do that a few times. Turning the ac on doesn’t change it as it will still do it with it running

With already replacing the maf, air control temp sensor, clean the throttle body, what’s my other options? I’m left with the idle control valve and the egr valve

Btw, no check engine lights or anything

Yep, looks like IAC and EGR valves is the next step. I know my car was doing something similar that was better after replacing the front cat as well.
