Dealer Throttle body cleaning
What exactly does the dealer do to clean out the throttle body?
$135 bucks seems like alot to just take apart the air intake and spray some throttle body cleaner into the throttle body.

More than likely they use Honda Top Engine Treatment. You can buy that yourself at the dealer's parts dept.
Alternatively, you can also use Seafoam (most automotive parts stores carry it...PepBoys, Autozone, NAPA, etc). I've used it by putting it in a spray bottle, then spray into the intake with the engine running. Press the throttle with your thumb to rev the engine as you spray as the engine will try to die (supposedly can cause hydro-lock if you don't).
The best way to clean is of course to remove the throttle body and use carb cleaner. You should buy a new gasket (or very carefully remove the old one to use as a pattern to cut your own). One reason removal can be better is because the passage from the throat to the MAP is very small and can become restricted by carbon. Simply squirting Seafoam or Top End treatment into the TB won't do much to clean that.

All Honda does is take the intake hose off and clean the front and back of the throttle plate, plus adds to different types of fuel additives to the tank. I know this because im a tech at Honda. I know what ya mean. Seems like alot of money for alittle work.

If cleaning with the TB on I wouldn't see this taking any more than half an hour unless you have an FI set up with an air to water aftercooler.

I swapped TB's a few weeks ago and wow, the inside of my original TB was caked with black grime. Probably because I'm FI and I don't have a catch can yet... But definitely needed cleaning at 57k miles.
