From what i know it's supposed to idle higher when cold. Probably not that high though.

Just kinda worries me about the high idle and oil pressure when it's first cold, the bearings I feel like its somehow screwing with them , but on other note it used to idle average between 1200-1500 on cold, and has jumped up quite a bit now, once warm though I can shut it off and start it and have it be at normal idle... Probably

To take stuff apart and clean

check the isc, and some boost leaks, you my find the problem there. Also check the throttle cable.

ya, iac and fiav ftw

Ill check the isc and fiav, i did boost leak test few days ago and had none.
