I also took the 2000 GS-400 to Autozone, and sure enough, it points to the TPS. Autozone quoted me $199. I went to O'Reilly's and they couldn't get the part but called Sewell Lexus: quote of $106 to O'Reilly's and $116 for civilians. Soooo, I am off to buy the TPS. Just hope I can figure out how to install it. Thanks to all of you on this post for the help. Oh, by the way, the problem was the VSC VSCOFF were both on at the same time and car would not go faster than 5 mph. I overrid this by hitting the VSC OFF immediately after starting, and was able to move regularly. Soooo (again), everything you guys mentioned is good as gold. I will probably also adjust the throttle cable. Cheers
