Default idle running high
I have a 2008 corvette 6.2 liter motor and automatic trans mission.The idle runs at 650 rpm in park, when I put it in drive the car runs away and it is idling at 950 rpm and will go 10 mph all day long without my foot being on the gas.Is there some kind of idle sensor that has to be replaced on the car.?
