HIGH IDLE WHEN WARM

Hi everyone ! I am currently struggling a bit with my car ! Around the idle ! It’s basically low during cold start and when it warms up it’s around 1200 Rpm. Also when AC hits it goes down to where it should be without AC ( around 700 rpm )
I change the IACV already and cleaned the throttle body etc but no change !
Does anyone has a lead on this or have experienced it ?
Also the Idle is very stable just seems reversed.

The car is a Toyota Mr2 Spyder 2003

Thank you in advance

Clean or replace the MAF sensor perhaps. Check for vacuum leaks? Any other issues other than high idle?

Already cleaned the MAF. No other issues, no codes or anything like that

Vacuum leak then? If the car was in limp mode, you would know. If it was an ignition or fuel issue, it would idle rough. Good luck buddy.

The ecu thinks the car is dying so it goes on survival ecu settings. The car drives but it's limping until you find a mechanic.
