Idle problem .. very frustrating

[Hikari]

This isn\'t on my subie but it is a general motor issue.

Recently cleaned out my iacv, checked the tps, re-routed the intercooler pipings and cleaned the throttle body.

Ever since this clean up I\'ve been noticing my car would idle funny..

1.2k ish rpm start up, drops to 1kish as it warms up but hear the car kinda fluttering and fluctuating during idle and when it is fully warmed up the car is at 1.5krpm ~ 2k rpm on idle.. fuck sakes.

So far i\'ve tested all the vacuum lines for leaks with a brake cleaner, also tried running the car without the intake and put my hand over the throttle car would die instantly. Ruled out vacuum leak issue.

Tried to reset the ecu by disconnecting the battery for a good few hours and put it back in as i forgot to do that while i cleaned the iacv. Nothing still bloody gives me a high idle.

I did not touch the idle screw.. running out of ideas now.

Any input would be appreciated as im getting stressed and out of ideas on what it could be.

update: tried doing a test a few people told me to try. With the connector still in with the iacv, turn the key to on position not start and the valve should move in and out but mine is just stuck . Is this test proving i have a bad iacv?

Yeah sounds to be stuck wide open
