GoldenStateSilverSport,
Was having the same intermitten idle problems. Almost took it to the Lexus dealer to get hosed for about 5oo to 700 dollars, but did a web search and found your post. Just finished the job. It took me about 1 hour and 15 minutes start to finish (thanks to your detailed instructions and pics). Seems to run better than new. You were so right about the factory tight screws and the large phillips screw driver. I used a socket wrench with a phillis screw adaptor and it helped in loosening.
Thanks again for the great post.
Bob
