High Idle when warm

Hi everyone I know this thread is been talked so many times but i cant seem to work out my problem!
Anyway just resolder my MAF circuitboard and the car runs much better at lower revs but when warm it stays at 1200-1400 rpm (which it didnt do before).
It is not a sticky waxstat as i have checked visualy and with datascan that the throttle is closed when idle.
IAC valve its stable at 24% but even if i close it with datascan revs only drop to about 1000-1100 rpm.
Idle adjustment bolt seems to be maxed out from what i have tried (thightening more starts slipping and dont wanna risk breaking it)
I reused the TB gasket (I know the manual says to replace it) and added some gasket paste aswell.
I am almost sure it must be a vacuum leak but all the hoses i took out are put together.
Just posting in case someone has any idea on whats going on or has it happen to them.
Thanks in advance!
