My (new to me) 2012 LR4 LUX revs past 2K rpm on the first start of the day. Foot is off the gas pedal. It settles down to around 800 RPM within 15 seconds. It still revs high when starting after it is warmed up, just not as high or for as long. The vehicle has 133K miles, good maintenance including timing chain guides and tensioners replaced. It runs smoothly and their are no other known issues. Does anyone else experience this?
