I have the same problem with my GS300. I took my car to my local Lexus Service Center and was told that one of my oxygen sensors was bad and in need of replacement. (337.00) parts and labor. In my car it is sensor #2 in Bank #1. I decided to find the part online and get a local mechanic who works on Lexus cars to do the installation. My total doing it this way is going to be a little less than 200.00. Good luck.
