Need Advise! Car Wants To Rev By Itself!

[-S-]

How did you manage to fix it? Am currently having the same problem with my rb25de where it's idle hunting between 1500 down to around 6-700 rpm. Have cleaned out the AAC valve, checked for air leaks done most of what I have read on here with no change. Thought it may have had something to do with the fuel filter as there was a little pool of fuel at the top of it, but since replacing it nothing has changed. Can someone please help me out here

Cleaned the aac valve. ..

now the only issue is it sometimes drop to almost below 500 rpm when shifting but so far have not shut off the engine so I'm cool with that!

Prior to this cleaning , sometimes engine would rev to 0 and shut off. [emoji44]

Guys... My car is possesed/idle hunt again. So obviously I knew what to do. Idled great after cleaning. Been years since I last cleaned it...
This time however I didn't fully remove the screw though as I'm afraid I might damaged the rubber oring like I did in the past... Plus it was really really hard to fully remove the screw. Pos oring must've been stuck.

So anyway it started idle hunting less than 2 days later !!! very mild but got worst over time... Now it's basically idle hunting in every traffic stop but it WILL go away after 20 or so seconds...

Any ideas where I should check again? Or is the iac valve tired/broken? Or maybe the solenoid? Or maybe the oring is damaged?
