Throttle Body cleaning

[Kevin325i]

So since nobody properly mentioned how to clean the throttle body I'm starting this thread so somebody can tell everyone how. I personally don't, I just assume you spray some alcohol in there and wipe the crap off the butterfly and everything else. I'm not sure and would like to find out however.

Somebody explain the procedure for cleaning the throttle body please.

I take a can of b-12 chemtool and hold the butterfly open...
Spray liberally, and use a rag to wipe up the crud that comes out. Then, action the butterfly a couple of times while spraying the chemtool onto the axis points of the butterfly. Put all the lines back on it, and start the engine to burn off any excess chemtool. Good as new!

If somebody has a better way, let me know.

No problem. I used to do this once a year on my old S13. The throttle body was probably the cleanest part on the engine... :lol:

i did this today to my moms volvo, i used stp throttle body cleaner that i got at autozone.

i sprayed it in the throttle body itself with the valve closed and cleaned the outside area of the valve, then i sprayed it onto a clean rag and used my finger to push the valve open then i cleaned the area on the other side of the valve (where the seal between the throttle body walls and valve meet), and the other side of the valve itself.

it made a HUGE difference
it was dirty as shit in there, and now the car runs fucking unbeleivably..i have 1000 more rpm's in all gears, it doesnt wind out as quickly, the engine isnt working as hard, and the manual shifting is much much smoother while accelerating, it accelerates much more quickly, and sounds better too.

i wouldnt expect these results though if your car is maintained well, not that my mothers isnt..its jsut that no one ever cleaned the throttle body before

(i also sprayed compressed air through the air filter and cleaned out the airbox..there were leaves in it lol.)
