When the car first starts it has good oil pressure 60+ lbs of pressure. they oil pressure sending unit was replaced. but when the car warms up it will slowly drop down to 20 lbs of pressure or less when ideling. if i give it steady gas it will go back up to 60 but if i jsut let it idel it will drop back down. what could cause this?
