i have searched and searched and cannot find a write up for the throttle body removal. does anyone know where i can get a write up on this i have a bad oil leak behind my engine and i want to change my valve cover gaskets. i also have trac control.

 

To take off just the tb it's 6 10mm bolts or nuts. Two above, two more below, a bracket comes off and then there are two more below.

 

if you search around you may find a better thread but this one helped me when i first did mine a long time ago. it shows a pic of the break down and i think it explains how to do it for the most part. best of luck the hardest part might be pulling off the coolant line on the bottom

Easy to do the only thing thats a pain in the *** is the coolant hose that runs underneath the throttle body and connects to it. Why Lexus put it there who knows...
