O2 replacement
sensor replacement ..
cold engine .. 10 mins to un-screw the old sensor . took 30 min to figure out how to get the connector out and remove it .. 5 min to screw in and snap in new connector ..
15 min drive .. CEL stays on but car drives great .. reset CEL by pulling EFI fuse .. drove nearly 1 hour and light has stayed off . car is driving strong again.

Make sure you clear your codes after you clean / replace anything. I am not sure how long it takes a Lexus to automatically clear itself. I thought I read 200 miles on a post somewhere but I am not sure. How is your car driving?
