Hey everyone, Just recently, my LS400 has developed a bouncy-type idle when starting it in cold weather (between 10-20 degrees F). It tends to go from 800-1200 RPMs sporadically. Any ideas on what could be the problem? From winters past, during cold weather start ups, the RPMs would be steady at about 1200 until it warmed up. Any input is appreciated. Thanks.
