My car starts off at high idle around 2.5k and sits there even when engine is warm, even when sits idle around 5 to 10mins. once i drive it around itll normalize to a 1k idle. what might be the problem?

Such problems are usualy caused by a faulty ISC ( Idle Solenoid control) valve within the throttle body.
