Hey every since it's been getting cold I have and high idle on startup. After the car is warmed up it stops. I can turn the car off and on and get no high idle. But if it sits for an hour or so and I start it up I get the high loud idle.
Has anyone had this problem or can tell me what the problem is. I have an 2000 GLE with 51000 miles

Thanks

 

What is the high idle speed?
How long does it stay up there?
