throttle body cleaning

This is probably a stupid question but how exactly does one go about "cleaning your throttle body"?

I swear that I cannot get the search function to work. Whenever I type anything in there it is pulling up no results?

step 1: buy TB cleaner
step 2: turn engine off and open hood
step 3: take air intake tube off TB.
step 4: spray TB cleaner liberally inside TB
step 5: remove all the black carbon buildup - use a toothbrush or your finger as necessary
step 6: keep spraying the crap out of IAC, TB and manifold till it looks like this:


optional: if you want to be very thorough, you should remove the TB from the intake manifold, disassemble it and clean it inside and out on a bench.

After spraying everything down, I always start the Jeep and let the cleaner "cook" for about 5 minutes.

okay, for a final stupid questions, the TB cleaner will not hurt the engine if it gets into it while cleaning the TB right? and obviously, you want to get as much of the black/build up type stuff on the rag or whatever you are using to whipe it up, but will it hurt the engine if a little gets in?

TB cleaners usually say to spray it in with the engine running, is this bad for the engine and/or oxy sensors/Cat downstream?

well if you open the TB blade while the engine is running...its gonna race the engine...i've never done it that way...TB cleaner is mostly acetone anyway, so it evaporates pretty quick. I always rev'ed the engine to about 2500-3000 after cleaning the TB, if done on the engine...just to blow some of the junk out that the acetone is going to loosen.

I always clean my TB with the engine running and it has never caused any harm to anything. That's after 182,000 miles of doing it that way too. The cans of TB cleaner I buy usually say "Sensor-Safe" on them.
