I have a 3rd gen. Should help, every car i have owned has slightly benefitted from MAF cleaning.

For anyone who finds their way to this thread, this happened to me too the first time I cleaned the throttle body. I just cleaned it again today and was sure to set the torque wrench to 15 ft lbs. I don't know what the deal is w/ these bolts but I could sense 15 was too much so I lowered it to 12 and that still felt like something was going to break.
I put away the torque wrench and went with the time-honored method called "Tagn!" ("That ain't goin' nowhere!"), just snugging them down until they felt tight enough.

Clean!
Very helpful procedure for cleaning the throttle body on 4Runner. Appreciate the post!

Also broke small fitting in the back
Old thread but also broke the little plastic fitting in the back of the air box.
Did a very weak repair with crazy glue to keep in place and reinforced later with epoxy.
How important is that fitting/hose?
Any suggestions for a more reliable repair?
Thanks

-Using the 10mm ratchet again loosen the clamps (A.) and remove the airbox mounting bolts (B.).
-Next undo the harnesses labeled C.
-Next undo the breather hose (D).
-Next detach the harness standoffs (E).
-Next remove the airfilter and detach it's 'lid' from the inlet hose.
-Next look at the back of the airbox and remove this rubber tubing (E). A quick twist and a pull should be fine. There's no clamp on it.
This is just an orientation photo showing the box loose but not completely removed.
And one after the box is completely removed.
Thanks so much for posting! Bought an 06 last summer with 230k. I drive a lot and needed something with 4wd. Cleaned my throttle body today and it was nasty. Took me 30 minutes to clean it off. Very easy to do thanks to your post.
Thanks for your post. I followed what you did but replaced the throttle gasket as well part #22271-0P010 ($12). My 2007 is at 156k and probably never had the TB cleaned in my records.
The new gasket was visibly wider than the old one, so maybe some wear, maybe just compression, but I did that. Can't say that it runs different but it shifts better in a cruise doing some pickups.
