Hey all. I am in the process of cleaning up my throttle body etc. 190k miles I think it is time. I have a question, there are 3 hoses coming off the bottom of the throttle body. Can you tell me what they are for? I dont want to take them off if I dont have to. Thanks so much. Pics attached. 96 ES300

how easy is it to remove the iacv to get to the stage you posted.

It was pretty easy. Just took the air box, intake tube, and disconnected some small hoses. Then unplugged the connector that goes to the valve. Then unscrewed the two screws to remove the control valve and I was there. Make sure you take your time with the 2 screws as they are very soft. Make sure you have a Phillips head screw driver that fits perfectly inside the head of the screws. And also, make sure you remove the hose that goes into the control valve so the throttle body cleaner can drain out the bottom. Otherwise your car will smoke like a chimney. Let me know if there is anything else I can try and answer for you. Or if this was the answer you were looking for.
