Default IACV Problem

Car: 2004 WRX
Mods: full exhaust, headers, tune

*freshly rebuilt as today was the first day i drove it after a year and i went 50 miles!
So today i was driving the car and it seemed like a TPS problem so i switched it out with a new ine. THAT problem went away and then it started idling up and down in park and neutral and kind of high around 1500RPMs.

I scanned te code and got a P0507 for IACV RPMS being higher than expected and also a P0519 for IACV syatem malfuntion.

Here's the thing.. I've cleaned it twice with gasoline, let it evaporate, then used alcohol and q-tips to clean it and made sure te valve moved freely.

The question: where or how should i go about fixing this problem? Buy a new one?
