FWIW,
I don't have access to the materials within the throttle body, which means I cannot validate my response...
It's probably not a good idea to use a "generic" carb cleaner on the throttle body.
A "solvent" that is approved for throttle bodies to clean gum, varnish, residue, etc off would be better advised.
I only mention this because I used carb cleaner on a domestic vehicle's TB and ended up with a rolling, rough idle due to the nylon bushings inserted on the shaft being "burnt" out from the cleaner.
If you are aware of this, or used an "approved" cleaner, then perhaps this might "enlighten" those that did not know. If someone knows the correct answer, or procedure...please share. I had problems, YMMV.
