Idling high only when hot outside
Over the past few days I've noticed my car idling at 1100 (ish) rpms when fully warmed up. At night, however, when it cools down outside the car ides normally at 750. I can also feel a difference in driving when the car is idling high. I have a small exhaust leak at the drivers side flange if this could have anything to do with it. No CEL or SES light on or I would have had the codes read to figure it out.
Thanks in advance to anyone who can point me in the right direction here.
