im going through my engine b4 i finish my swap to paint it and clean it and make sure all the internals are fine. anyone have any suggestions for cleaning the inside of the trottle body and the other 2 peices that have build up in them?

The best way to clean the intake and throttle body is to remove it and take it all a part so you can get into it easier. It took about 5 cans of carb cleaner when i did mine.

i have it all apart right now. do you just scrub it out or what? i just dont want to hurt the inside.

Make sure you use throttle body cleaner specifically...So it won't affect the TPS.

I'd use the throttle body cleaner. Let it soak for a couple minitues then it should wipe off easy with a rag and cotton balls.

Toyota's FSM recommends using carb cleaner (probably just as good as TB cleaner) and removing the TPS before cleaning the throttle body. Just put on a couple of precise matchmarks and you'll be good to go.

Use a stiff plastic brush and just go to town with it. You won't damage the cast aluminum if you use plastic.

I put mine in a parts washer and scrubed it for about 2hrs. This only got a little bit out. Came home and tried carb cleaner and an old tooth brush. All that did was move the gunk around inside the intake parts. Then I took all the parts to the car wash and hit it with high pressure soap. This did the trick and blasted all the crap out for a buck fifty. It was clean as new. Just wish I had read about removing the tps first.
