Most likely IACV. Just do a search here for "IACV" for more info than you will ever want to know.
Well removed the IACV it was stuck could not move the magnet, sprayed carb cleaner down the hole in the throttle body truned the magnet by hand a bunch of times till it was free and smooth.
Car know runs fine........wow Thanks so much for the help. That took all of 15 min to do and I am sure Lexus would have banged me for that.....
