How to fix high RPMs

[TIGGZ_S13]

I already checked the timing (lamp), adjusting the iacv wont help it just raises the rmps (its already all the way). What else can i do to lower the revolutions?
I dont think its the tb screw either. I heard the intake manifold has 2 ways to adjust idle. But idk maybe im missing something. Can anyone help?

if youre talking about idle, a vacuum leak can cause a high idle

Check your coolant temp sensor.

what engine/mods are you using?

Yeah i was referring to idle. Removed all vaccum lines except neccesary ones (booster, fpr, iacv). Ka24de just headers. How can i check the coolant temp sensor?

Get a can of brake cleaner and spray all around the intake and up to the maf. If the idle changes you have found your problem.

Have a great day,

In the manual, take a multi meter and look at the ohms for spec.
