This is how I clean the throttle body of a 2010 Honda CRV. I remove it, I clean it, and i reset the idle by using the idle relearning procedure for the PCM/ECM.

Relearning Procedure
Procedure
1. Make sure all electrical items (A/C, audio, lights, etc.) are off.
2. Reset the PCM with the HDS (or disconnect you battery and wait between 5-15 min)
3. Turn the ignition switch to ON (II), and wait 2 seconds.
4. Start the engine. Hold the engine speed at 3,000 rpm without load (in P or N) until the radiator fan comes on, or until the coolant temperature reaches 194 degrees F (90 degrees C).
5. Let the engine idle for about 5 minutes with the throttle fully closed.
NOTE: If the radiator fan comes on, do not include its running time in the 5 minutes."
