M500 Posted February 16, 2007 Posted February 16, 2007 Should I be worry? My 06 LS430 alway idling above 1200 RPM. Its start at 1800 and gradually to 1500 and then 1200. Its just stay there after that for more then 5 minutes unless I took it out and drive it then it'll finally do down to 700. Is this normal?
