Question S14 HighER idle after adjustment?

Ok, so, i have a 95 s14. When I got the car the idle was around 1200-1500. So I decide to investigate fixing that issue, and come across idle adjustment. I unplug tps, mess with bolt, yata yata.. start car up and now its over 2k? How can the idle increase after this?

Did you do the procedure correctly? Unplug cas. Start car. Rev to 2k twice. Adjust iacv so the rpms is 750-800. Plug cas back in. Done. Some ecu's will let you adjust idle maybe 100 rpm or less. But I think it messes with timing too.

Wrong!
it's, tps! and rev the engine to 3k x3 to lock into Base idle/timing mode, he's already idling at 2k BTW.
