Weird Idle Issues (Researched Already) Options

[955SFE]

I have this weird idle issue.
Idle is either high, low or normal....at any random condition. It doesn't stall.
When idle is high, I just rev the engine a little and Idle goes back to normal.

Things I've replaced:

Spark Plugs (OEM)
Wire set (NGK)
Cap/Rotor (OEM)
Cleaned the TB
Thermostat (OEM)
Idle issue started after I replaced all of that ^

I want to clean the IACV but I can't seem to find it or I don't even know if it has one. ( Can someone post a picture of the engine bay and circle it, thank you)
No codes. Passed Smog with flying colors.
Ignition timing sits a 13* (I hope that's normal)
Car runs fine. MPG is 25-27 combined.
Today I'll reset the ECU (Pulling out the Hazard, EFI, ECU fuses).
I also don't hear or see any vacuum leaks.

Engine has 95k miles. MT
I did search some posts but none reported back with a solution.
Thank you.

Cleaned the IACV. IACV was dirty but it didn't solve my problem. I'll be checking the resistance/volts on the IACV and TPS this weekend. Any other suggestions?
